Trevor has asked us to fill out the Periodic Table of Dragons (see links above). Blogs and emails seem a clumsy way of doing it, so I've create this thread. I'll update it periodically (pun intended), as people suggest new blurbs about each elemental dragon.
Hydrogen: While no known hydrogen dragons exist, the closest thing in the game might be either the gas spore… or, sadly, the gorbel. Article
Helium: These dragons are known to float over parade routs and possess comically high-pitched voices. Article
Lithium: Lithium dragons have smooth silvery scales that become crusty and edged with white as they grow older. Not very physically impressive, Lithium dragons are enamored of psionics, especially empathy and mind controlling effects. They breath fire when they must, and while it doesn't seem to do a significant amount of damage, the ongoing damage is coupled with a nasty penalty to saving throws while it lasts. ChimericPhase
Beryllium: Sometimes called the emerald dragon, this dark-green colored dragon is known for its complex clan structure and heavy consumption of alcohol. It has been known to quarrel violently concerning relatively minor matters of religious doctrine.just_be_glad_now
Boron:
Carbon: After slumbering for millennium within the ground, this creature can emergs as a diamond dragon. Fumes from its breath weapon have been thought to raise global temperatures. Article
Nitrogen:
Oxygen: This dragon is pretty common, but rarely seen due to its invisibility. It is very territorial, and reacts violently with almost all other types of dragons. These dragons are very highly valued among adventurers, since their breath weapon can actually keep people alive. Three oxygen dragons can combine their breath attacks to block ultraviolet light. Mixula
Fluorine: Fluorine dragons are the most temperamental and violent dragons in existence - they freely attack anything without a moment's hesitation inflicting masses of damage even upon the strongest of opponents. They are absolutely fearless and virtually impossible to contain or control! Noroth
Neon: When excited, Neon (Ne) Dragons glow brightly in an array of garish colors. Their breath weapon is a dazzling spray of flashing colors. The most mercenary of all the dragons - although they prefer simply making money to fighting, being among the most fragile of dragons - neon dragons can be hired to make all kinds of bright displays, often turn their lairs into casinos in order to enhance their hoards with the winnings. Enlightened1
Sodium: Its breath weapon raises blood pressure to unhealthy levels. Also extremely dangerous around water. Article
Magnesium: This dragon is originally silvery-white, but unless it concentrates to douse them, it's skin burns with white hot flames. In that case, it gives off a bright light as well as tremendous heat. Its fiery breath weapon clings to skin. Magnesium dragons are incredibly fast. They live for the day, and are generally unable to plan ahead or show concern for the well-being of other creatures. Gomeztoo
Aluminium: If there ever were a dragon minion, this fellow would be it. Article
Silicon: If we're stretching the definition, the desert-dwelling brown dragons (formerly sand dragons) are closest to silicon. Sadly, they do not transform into glass when attacked with fire (but we think they should). Article
Phosphorus: These dragons are found in several varieties: white and red are the most common, although black and violet are found more rarely. They are often confused by adventurers for their chromatic cousins, but can be distinguished because they are not nearly as hostile as chromatic dragons, often seeking to bond with other individuals. White phosphorous dragons are known to glow in even magical darkness, and have a special power where they set their own scales aflame. wrecan (alternate by Noroth)
Sulfur: While they do not have breath weapons, they can still emit deadly gas attacks. Article
Chlorine: Green dragons once breathed a cloud of dangerous chlorine gas (or bertholite, as it's also known in warfare) and had the formal name "Draco Chlorinous Nauseous Respiratorus". A pure chlorine dragon, though? Possible hired by wealthy dungeon owners to swim in their magical pools and keep them clean. Article
Argon: Argon dragons just sit around without doing much. They seem to follow the philosophy that it is better to avoid confrontation at all cost, so they are very prone to just swiftly escaping combat before it starts. Argon dragons glow blue when attacked with lightning. Drokles
Potassium: Amongst some of the most vain of dragons, this aquatic species will attempt to spend the entirety of it's life beneath the surface of the sea, for once it emerges into the air the creature's magestic silver scales will quickly tarnish to a dull gray. As soon as possible following such an incident, the potassium dragon will find a seabed of coarse sand or abrasive rock to exfoliate the thin layer of tarnish to reveal a fresh gleam of silver beneath. CraggleRock
Calcium: This small dragon has whitish, stone-like scales and inhabits burrows. While it lays eggs as normal for dragons, females are capable of feeding their young through producing milk. Its jaw-shape resembles that of a duck's jaw, giving it an odd-looking, rounded snout. just_be_glad_now
Scandium:
Titanium: This dragon has scales tougher than iron or steel dragons. Article
Vanadium:
Chromium: Appeared back in Dragon Magazine #170. Originally "the most evil and greedy of all ferrous dragons. They seek treasure and are matched only by red dragons in their obsession for more." In battle, they breathed clouds of freezing mist and solid bolts of ice, and could cast their own version of the flesh to stone spell: flesh to crystal. In keeping with the true properties of this element, however, we feel chromium dragons should have instead been masters of magnetism, and with highly colored scales. Article
Manganese:
Iron: Appearing in Draconomicon: Metallic Dragons, "violent and ill-tempered, iron dragons and undoubtedly the most brutish and vicious of the metallic races." Despite elemental iron's habit of oxidizing, iron dragons do not rust as they age (but which would make a compelling look for ancient iron dragons) nor do they fear rust monsters. Article
Cobalt: Appearing in Draconomicon: Metallic Dragons, "they suffer no traveler to pass through their lands without bending knee and acknowledging their power, and anyone who refuses quickly comes to regret that error." Since cobalt was also once known as "kobold ore," we highly endorse a cobalt dragon/kobold army team-up. Article
Nickel: Appeared back in Dragon Magazine #170. Originally the weakest of the metallic dragons (so 1 nickel dragon did not equal 5 copper dragons), they breathed a cloud of deadly vapors, occupied the same environs as black dragons, and caused mass irritation/itching/rash (seriously). Article
Copper: Appearing in Draconomicon: Metallic Dragons, "charismatic, sly, and witty, copper dragons are by far the cleverest and most interesting of dragons—or so they say." Article
Zinc: Thought to mate with copper dragons to form brass dragons, just as copper and tin dragons form bronze dragons (and gold and silver dragons form electrum dragons). Well, so we conjuncture. Article
Gallium:
Germanium: These grayish-white dragons have particularly good eye-sight, both in the visible spectrum and the infra-red. They are not seen that often - In fact in one of Elminster's minor works on the ecology of Faerun, he used the idea of ecological niches to predict their existence 18 years before the first recorded encounter with one. David_B
Arsenic: Clearly, the most venomous of dragons; their blood is sought after by assassins, poisoners, and creepy old aunts with a penchant for murder. Article
Selenium: Selenium dragons live on the moon, and have a stony skin that blends in with the moons white and purplish gray surface. They can appear larger than they actually are, can reflect radiant, illusion, and psychic attacks back on their attacker, and they naturally displace. Their breath weapon is radiant energy that can daze and blind, and their aura of fear causes momentary madness where victims attack their nearest ally. Moonglum
Bromine: Bromine Dragons live in caves near to the sea and have one of the most fearsome breath weapons - they expel a cloud of deep red corrosive, poisonous gas which if you survive the effects of the poison, leaves you with severe burns effectively removing you from combat for several rounds. Noroth
Krypton: Its breath weapon reduces epic tier heroes to their whimpering 1st level selves. Article
Rubidium:
Strontium:
Yttrium:
Zirconium: Often tries to pass itself off as some kind of astral diamond dragon. Their hoards are similarly over-valued. Article
Niobium:
Molybdenum:
Technetium:
Ruthenium:
Rhodium:
Palladium: A fierce but small dragon, it enjoys living in Rifts. An inveterate game-player, the Palladium Dragons have a vast imagination and a playful spirit. wrecan
Silver: Appearing in Draconomicon: Metallic Dragons, "silver dragons embody all that is honorable about dragonkind." Article
Cadmium: Occasionally pairs with a nickel dragon to create batteries of magical energy. Article
Indium:
Tin: These dragons are tiny in size. Any individual tin dragon might have the morphology (though in miniature) of any large metallic or chromatic dragon. Tin dragons are all vulnerable to fire. Once per day a tin dragon duplicate the breath weapon attack of any of the large metallic or chromatic dragons. Moonglum
Antimony:
Tellurium:
Iodine: This dragon lives most of its life underwater. It feeds from plant and other matter found in swampy lakes and ponds and in fetid pools in which things have been left to decay. As it feeds, it creates the side effect of actually cleaning and purifying said water leaving behind a strange bitter aftertaste one can learn to recognize. Once a body of water has been cleansed the dragon rises from the depths and searches out a new, more suitable, home. This dragon does not like to be disturbed. It will aggressively attack any who enter its chosen pool and any who threaten it as it migrates. The Iodine Dragon has sharp and posionous teeth and can manipulate its sharp scales to cut any creature it rubs against. It is fast and deadly in the water and can also move quickly on the ground but has limited flight, capable of gliding only two to three hundred feet at a time. Although primarily a loner, occasionally a mated pair can be found; likely with a nearby cache of eggs. Shaadow
Xenon:
Caesium: These dragons are prone to violent outbursts and sudden fits of temper. They react quickly (Initiative bonus +20) but are very vulnerable to water based attacks. David_B
Barium:
Lanthanum:
Cerium:
Praseodymium:
Neodymium:
Promethium: Fire leaks from between the scales of these dragons -This coupled with their fondness for humanoid races often leads to unfortunate village fires. Once a town or civilization finally warms up to it's Promethium friends, the locals can often be found roasting marshmallows and hot dogs on/with them. WotC_Trevor
Samarium:
Europium:
Gadolinium:
Terbium:
Dysprosium:
Holmium:

Thulium:
Ytterbium:
Lutetium: Lutetium Dragons wander from place to place with no discernible purpose - it has been suggested that they take delight in being studied by others who seek to understand their true nature. Noroth
Hafnium:
Tantalum:
Tungsten: Appeared back in Dragon Magazine #170. "Tungsten dragons are a no-nonsense species dedicated to the preservation and expansion of the forces of good. Unfortunately, tungsten dragons usually limit this preservation and expansion to their own domains." For whatever reason, tungsten dragons breathed a cone of blasting sand, and could cause spontaneous combustion in their opponents. In keeping with the true properties of this element, we'd suggest that tungsten dragons have a high resistance to fire, and with scales commonly used as filaments in dungeon explorers' lanterns. Article
Rhenium:
Osmium: Osmium Dragons are exceedingly rare and can only be found in and around collapsed stars or pockets of void deep within the Astral Sea. Their super hard scales are a lustrous silver colour with a distinctive bluish sheen. Their breath weapon is a gas which reacts with the air to produce dreadful fumes which cause blindness. Noroth
Iridium:
Platinum: Appearing in Draconomicon: Metallic Dragons, "The god of honor, justice, and nobility, Bahamut is known as the Grandfather of Dragons or Lawbringer, but most often called the Platinum Dragon. Though the deity can appear in many forms, he is usually portrayed as a powerful dragon with platinum scales, the form he takes on when he goes to battle." Of course, this form deviates from his reference in Arabian mythology—that of a massive fish, holding up a bull with 4000 eyes, holding up a ruby mountain, holding up… well, that Bahamut holds up quite a bit, it turns out. Article
Gold: Appearing in Draconomicon: Metallic Dragons, "also called royal dragons or imperial dragons, gold dragons are the apex of an already unimaginably powerful race." Article
Mercury: Appearing in Draconomicon: Metallic Dragons, "mercury dragons are a little bit crazy—but there's definitely a method to their madness." Article
Thallium:
Lead: The heaviest of dragons, they cannot be pulled, pushed, or shifted; and their aura draws enemies 1 square closer each round. Article
Bismuth:
Polonium:
Astatine: Astatine Dragons are rumored to have only ever been seen for the briefest of seconds before disappearing into nothingness leaving death in their wake - no one who has ever caught a glimpse of one has survived long enough to give an accurate description. Noroth
Radon: Lurking in basements, radon dragons breath a sinister poisonous gas that slowly destroys the surface dwellers that innocently build their own homes atop the innocuously appearing dragon's lair. wrecan
Francium: Francium dragons are the rarest of the naturally occurring metallic dragons. It is usually spawned when an actinium dragon (which has a very unstable temper) splits into two lesser dragons, in much the same manner as Io did, one of them being the francium dragon, the other being the helium dragon. Since francium dragons on average live for 22 minutes it's hard to believe that anyone has actually ever seen one, but scholars hypothesize that it has an extremely high temper and will attack almost anything it comes into contact with and is very dangerous in the presence of water element dragons. Francium dragons die while releasing a burst of radiant energy, and it is believed that new dragons are born from this event such as astatine, radon or radium dragons. Drokles
Radium: Radium Dragons glow in the dark and have an acute sense of time. They are resistant to radiant damage. Their breath weapon does radiant and poison damage, and causes a bone mutating disease that slows and then immobilizes the victim, before killing them. They have an innate aura that causes those near them to glow (losing concealment, etc.) and that can cause the radiant dragon disease. Radium dragons that are ancient or older (ancient radium dragons have reached at the age of 1602 years), can change to a deadly cloud of luminous gas once per encounter. Moonglum

Plutonium: We've actually faced this dragon in Munchkin… the fiercest monster in its starter set. Article
Americium: While Tiamat has five heads, this creature has but three: that of a red, white, and blue dragon. Breathes explosive pyrotechnics, mainly for large celebratory displays. Article
Curium:
Berkelium:
Californium: This dragon doesn't just have minions (his entourage) but also an agent… and a slight residuum habit. Article
Einsteinium: The wisest of dragons, with a crown of wildly jutting scales. Article
Fermium:
Mendelevium: Mendelevium dragons are creatures of order and like to organize everything they can. The lair of a mendelevium dragons are neat, ordered, and treasures are arranged based on different similarities (diamonds in one chest next to rubies, sapphires, and then emeralds). Because of their organized nature, they tend to prefer to use abilities to dominate and command enemies, directing them where to go and whom to attack. Arymetore
Nobelium: Armed with a breath weapon capable of causing explosions, this dragon is quite deadly. However, it uses its breath weapon to dig its underground lair and to extract minerals, feeling that its use as a weapon is inappropriate. They typically worship gods of healing and forgiveness, due to their extreme remorse when a hiccup or burp causes the death of a friend. just_be_glad_now

Copernicium: Possibly the least egotistical or self-centered of dragonkind, these creatures do not subscribe to the seemingly common held belief amongst dragons that everything revolves around them. This unusual attitude may originate from the fact that the species was only recently given birth during intense arcane experimentation that took place at the White Locus Academy. As such, all currently living copernicium dragons would be classified as young examples of their species.CraggleRock
Unobtanium: This legendary Dragon only appears in the aftermath of a devastating environmental catastrophe such as the destruction of one of the old and living forests. Sometimes called the "Gaia Dragon" this beast can summon an army of creatures native to the region to battle those who have performed the desecration. The Dragon itself can lay waste to armies, as it gains strength from the very number and power of its foes. It has been theorized that this dragon may actually be a puppet, controlled remotely by one of a group of powerful sorcerors known as the Green Algore'.
53. Iodine: This dragon lives most of its life underwater. It feeds from plant and other matter found in swampy lakes and ponds and in fetid pools in which things have been left to decay. As it feeds, it creates the side effect of actually cleaning and purifying said water leaving behind a strange bitter aftertaste one can learn to recognize.

They typically worship gods of healing and forgiveness, due to their extreme remorse when a hiccup or burp causes the death of a friend.
#4, Beryllium dragon.
Sometimes called the emerald dragon, this dark-green colored dragon is known for its complex clan structure and heavy consumption of alcohol. It has been known to quarrel violently concerning relatively minor matters of religious doctrine.
