How many electrons does Br lose or gain to fill its octet?

The reaction A 2B C 2D is run 3 times. In the second run, the initial concentration of A is double that in the first run, and the initial rate of the reaction is double that of the first run.

A diatomic molecule shares three pairs of electrons. What type of bond is present in the molecule? A single covalent bond because each atom requires one more electron to complete its octet.
