any element can be radioactive, all depends on how many isotopes it has, even helium can be radioactive

My point exactly, but do you think everyone understands that, and uh, an isotope is a "variant" of normal atom of a specific element and does not make something radioactive, it is the number of neutrons, that make different isotopes and different isotopes depending on the number of neutrons can or can not be radioactive. For example Carbon 14 is radioactive and has gained 2 extra neutrons than the standard Carbon 12 atom. This is so much fun talking about physics isn't it!:D:D:D

I'm going to assume he meant neutrons, not isotopes.

sorry it has been two years since I have been in chemistry which is when we learned that, I meant nuetrons

It is quite alright, us humans do not have the capabilities [I]yet[/I] to permanently store information in our brains like computers can ,but of course we have to tell them when to do so, which I suppose is an upside, and computers have specific pieces of equipment that are used just for storage.:(:)
