# When a sulfur (s) atom becomes an ion, what charge does it usually have?

May 24, 2018

Well, sulfur is a Group 16 NON-METAL...

#### Explanation:

And thus we might expect its chemistry to mirror that of oxygen, which commonly forms an ${O}^{2 -}$ ion. And while other oxidation states are available, sulfur does readily form sulfide ion, ${S}^{2 -}$...……..

$S \left(s\right) + 2 {e}^{-} \rightarrow {S}^{2 -}$

Under oxidizing conditions, we could access sulfate dianion, i.e.

$S \left(s\right) + 4 {H}_{2} O \rightarrow S {O}_{4}^{2 -} + 8 {H}^{+} + 6 {e}^{-}$
