Fun with Chemistry: a Ferrous Wheel

Right. If you're checking out this shirt, you probably like corny chemistry jokes, so here's another for you:

Two atoms walk into a bar.
One atom stops and says to the other, "I think I just lost an electron."
The second atom asks "Are you sure?"
The first atom replies, "I'm positive!"

*rimshot*

A ring of ferrous ions (Fe+2) is printed in white on this 100% cotton, maroon shirt.
