I'm working on chemistry homework, and I just came across a few issues I don't understand. For one, why isn't Sodium Bromide NaBr2 (Online sources show it as NaBr)? Isn't Bromine a diatomic element?

Bromine is a diatomic element, Br2. But the bromide ion is not Bromine. Bromide is monoatomic, and has a charge of -1.
Okay. Sorry if this is bothersome, but...then what causes Beryllium ChlorIDE BeCl2? Doesn't chlorine have a charge of -1 as well?
Chlorine is an element, it has no charge.
Cloride is an ion, -1
