[NE] Artificial hydrogen Tests Quantum Theory.

Scientists have created ultra-light and ultra-heavy forms of the element hydrogen, and have investigated their chemical properties.

Donald Fleming, a chemist at the University of British Columbia in Vancouver, Canada, and his colleagues generated two artificial analogues of hydrogen: one with a mass a little over one-tenth that of ordinary hydrogen, and one four times heavier than hydrogen. These pseudo-hydrogens both contain short-lived subatomic particles called muons — super-heavy versions of the electron.
Somebody call Schrödinger!

Hmmmm, very interesting!

I'll be sure to talk with my chemisty teacher about this, chemistry is so fascinating.

I'm still only very much a novice in chemisty and the likes, mind describing what a Muon is?

They're leptons (in the same category as electrons, as they're not made up or quarks like neutrons and protons). They're unstable and when they decay, they release 2 neutrinos and an electron/positron (depending on charge).

So the classification of an atom is dependent on it's overall charge, not the number of protons? High school chemistry lied to me again :/

I wonder what would happen if they made a nucleus consisting of equal numbers of protons and muons...

I wonder how the light hydrogen works. Muons have a negative charge and are more massive than the electron. Shouldn't they be repelling?

Okay, thanks for the explanation. I understood most of it. (I'm not even through high school chemistry yet, one more year. Nor Physics.

Seriously, that's ALL High school chemistry is. Lies upon lies. My old chemistry teacher would say that everyday. "So what they taught you in year 9? That's a lie, you do it this way."

interesting. hydrogen is pretty simple though lol

In the picture shown, that is a positive muon (they can either be positive or negative)

I think even high-profile chemists feel that way. There is so much about the quantum world we just don't understand.
