Elemental Coin Series

Imagine all the elements on the periodic table made into coins. A company has been working out the kinks the past few years. They started with base metals and now working on glass ampules, coin shaped, containing the gasses. I dont care much for the sulfur or arsenic coins, but many of the exotic metals are too cool to pass up.

Keep the Krypton element coin away from Superman!

 

I feel your pain. If you'd spent 20 seconds looking it up on Google, where would you have found the time to make another sarcastic post?

 

I bought all the coinage metals except Pt and Au two years ago. Neat little things!

 

17 seconds. I'm fast.

 

Thanks. The tungsten coins were wearing out their dies. Osmium coin interesting. Irridium too.

 

I was basically asking the OP to do the same.

 

I know. Hopefully, this won't fester into a full blown MMA cage match.

 

"Let's get ready to rumble" lol just kidding.

 

I'm forever losing my Oxygen rounds.....

 

The neon coin will light up orange red when an electric current runs through it. The sodium coin will explode on contact with water. It'll be encased like the other toxic elements. Direct prolonged sunlight on the hydrogen coin would be bad. Theres several other reactive elements. Its a very interactive coin set. Science and coins yay!

 

Why? What am I missing?

 

Direct sun on any of the gasses causes expansion through heat and you risk losing gas through any micro crack. While it isnt an open flame, the glass could intensify light like a magnify lens n poof. Ever hear of the Hindenberg? Granted that was static buildup, but hydrogen doesnt get along with flames.

 

If they ever make uranium pennies, i'd have fun smashing them together making "kabloom" sounds. I like collecting ore too. Uranite and pitchblende pretty and you can put dry ice next to them and watch protons fling off. Trinitite isnt an ore but its cool too. I digress, back to coins. Hmm i wonder if theres an ore chat...

 

I'd say a coin-size volume of hydrogen won't cause much damage, even if it's ignited all at once. Even if it's mixed in the optimal proportion with pure oxygen, you wouldn't get more than a loud pop.

I say this as a former chemistry hobbyist who's heard lots of those pops.

I'd be a bit more cautious with the fluorine coin, if they were ever foolish enough to produce them...

 

Our chemistry teacher took an empty pringles can, flipped it upside down, filled it with hydrogen, flipped it upright and lit the top. He explained as the hydrogen burned down, oxygen would combine until it reached its optimal mix. He paused for effect and the can exploded in half. It was a great demonstration!

 

The problem with a hydrogen "coin" would be keeping it in. The hydrogen atom is so small that it will fairly easily diffuse through any plastic holder and be lost. A glass capsule would have a better chance of holding it. Any pressure increase from direct sun exposure would be very slight and would not greatly increase any gas loss. Heat concentration from a magnifying glass effect wouldn't do anything because hydrogen itself doesn't burn or explode. You need an open flame or spark plus the presence of oxygen. No oxygen inside the capsule with the hydrogen, no flame/explosion. You could heat it up until the capsule melted and nothing would happen.

 

I hear ya. It really irks me when an OP only posts half a thought, and then expects you to Google it to find out more. If you really cared to share the information, tell me the whole story! Sure, I could google it, but that's not the point.
