Question

What is the oxidation state of elemental bromine?

Answer 1

Of elemental bromine....?

Explanation:

Why it's ZEROVALENT. For the `Br_2` molecule, each bromine atom has neither donated NOR accepted an electron. And thus we have zerovalent bromine.

Of course, in its compounds, bromine can assume oxidation states of `+VII` down to `-I`.

By the way there are few things in a lab as corrosive as bromine. You treat it with great respect.
