A curiosity I thought I'd share

When I worked on Artificer's Handbook a couple of years ago, I wanted to include sections for all the various components that people could use to create magic items. So, we included the obligatory section on gems/minerals, plants & herbs, and a few other oddities. I also wanted a section on metals, and as I started writing it, I kept thinking of more and more metals, and then it occurred to me - I was trying to recreate the periodic table of the elements, since my list had things like gold, silver, lead, tin, etc.

So, through a couple of really boring meetings at work, I scoured through some great websites devoted to the PTotE, and created a rudimentary D&D version of the table.

It was a fascinating excursion into the complex world of chemistry, one that I admit was largely unfamiliar with.

Ultimately, I made the decision to exclude it from the book, since I felt like it needed a lot more work.

I gave it to our editor after the book was published, hoping to see it as a web enhancement, and she wanted me to expand it, including things like "hardness" and hit points to make it more useful. Unfortunately, I can't even begin to speculate on what the hardness of "iridium" might be, so I never bothered to complete that.

But maybe someone here does. A lot of the elements are gases, or powders, or chalky substances, so only a few of the things would actually have any kind of hardness or hit points.

But I thought I would share the file with the good people here as a little thanks for all the fun times I have here. And if people want to come up with hit points/hardness values for all the metals in here, that's fine by me, too. While this has some limited use for D&D games, it could make a great addition to a d20 modern game.

Y'know, since the solid elements have a hardness scale associated with them (Brinell hardness test, Mohs test,etc.), you could get a ballpark figure for each element.

I've always wondered about iridium, which is supposed to be some strong stuff, and what I find is that its Mohs "scratch test" is about 6.5, whereas Titanium's is about 6, so not much stronger than Titanium or steel. Mohs however is not the best scale, Brinell's scale seems better for "stress testing."

mang,

when i was in school i don't think the periodic table went above 103.

It still doesn't, as far as I'm concerned - any substance whose half-life you can measure in picoseconds ain't a real element, in my book. ;)
 

Iridium was in the news recently, in fact. They discovered large veins of it under the snake mounds in Ohio. They speculated that a meteor must have impacted there at some points, since it's so rare on Earth otherwise.

Crothian, I really enjoyed writing it, but it took up too much room, and I opted to cut it out of the book. I would have liked to see it in there as well, but that's the way the cookie crumbles.

here is the text writeup that accompanied it:

Periodic Table of Elements
Everything in the known universe is built from common elements. While some elements were known in ancient times, most were not, and some that were once considered elements were later discovered to be compounds.
The elements are presented here to spark imagination and broaden the medieval horizons of alchemical building blocks. For instance, bronze is an alloy formed from copper and tin. Perhaps on your world, craftsmen have bonded gold and lead, creating an alloy that shimmers like gold, and has unique magical properties. Furthermore, you could add new elements to the list, namely mithral and adamantine, which are fictitious metals. Or, you could make them alloys formed of some real element and magical energy. You can also play around with the chemistry of the elements. For instance, salt is sodium and chloride. An ancient recipe for magical goggles might call for sea salt, but all it really needs is sodium. When the magic item is created, the sodium from the salt is consumed, leaving chlorine gas that consumes the oxygen in the air, knocking everyone unconscious.
The date of discovery is listed for each element. The timing of discovery is affected by the nature of the world, and in turn affects the history of the world. There are no constraints in how you define the elemental makeup of a fantasy world. Perhaps indium is more common than iron, and everyone walks around with swords made of indium. Or, perhaps copper is more rare than silver, so copper coins are more valuable than silver coins. Some elements are discovered earlier than the dates listed here. Just because promethium was not discovered until 1945 does not mean that it cannot be a staple of alchemical research in a fantasy world.

Components in a Futuristic Setting
In a futuristic or modern-day setting, the sky is the limit when it comes to components. Requiring someone to find strontium in a medieval setting is unfair, but not in a futuristic or modern day setting. Imagine the look on your player’s face when you tell her she needs rubidium and germanium to make that magic wand she wants so badly. Most elements in the periodic table do not occur freely in nature, and thus would be unavailable in a medieval setting in pure form. Many elements at the higher end of the spectrum are unstable and radioactive. Some exist only briefly. Some react to air and can only be kept in pure form in a vacuum. In addition to the difficulties imposed by isolating some elements and containing them in a safe manner, there is also the problem of acquiring the element. Where does one get krypton or einsteinium? The difficulty in acquiring the component should have direct correlation to the power level of the magic item created. Forcing the creator to acquire costly, rare, and difficult-to-find components for a 1st level wand is unnecessarily harsh, but certainly reasonable for an artifact or similarly powerful magical item.

Indeed. There are only 92 naturally occuring elements, the others on the PtoE are all 'made'. Looks good die_kluge!
