All right, so I think this is highschool level. I'm homeschooled, and at a highschool level as far as I know.
Anyway, I've been on a chapter in my book on the system we have for naming monoatomic ions, and polyatomic ions.
My question arose when I saw a table listing some common monoatomic ions--if an atom is an ion, does this mean it has to be bonded to another atom?
Is it possible for a single atom to be an ion on its own, unbonded? If so, where does the extra electron come from--or where did one go?
