Seven

Okay, thanks a lot guys! Also, yeah, I meant Be. I have a tendency to mix that and magnesium up for some reason. Anyway, I got my essay in, and my teacher said it looked pretty good. Hopefully an A.

Google's been giving me some pretty vague results on this subject.... I have to write a report on one the the elements (for me, lithium), and I decided I'd do a little extra and have a little section on plasma. However, we've never covered it, so I don't really know much about it. Does a gas become a plasma when an electrical current passes through it, or at a certain temperature? Both? Are all the electron shells stripped of electrons, or just some? At what point does lithium become a ionized/recombine? Is that even possible? Thanks a lot. =) PS- I'm talking specifically about 7^Li, but 6^Li is stable so I guess that could work for an answer. PPS- Is it true if you bombard 7^Li with protons it turns into 8^Mg and has a nuclear reaction?
