I am at the beginning of self-studying chemistry and one question I have is quite simple yet I can't seem to get an answer that people agree on, or I am not searching for it properly.

The question is whether Sodium can form an Anion. I know it can form Na+ but some texts I have read say it CANNOT form Na- yet others say it can. I am unsure if that is just new information included in some texts and not in others or if there are extenuating circumstances.

Thank you for the help in advance.

P.S.: Since I am here, are there any good textbooks for self-studying chemistry?
