It is because of it's electronic configuration.

Bromine is a liquid because the intermolecular forces are strong enough. So, that it does no vapourised.
Br forms diatomic molecules and van der Waals interaction are sufficiently strong, and it belongs to the halogen group.

The uses of bromine is :
Bromine compounds are used as pesticides, dyestuffs, water purification compounds, and as flame-retardants in plastics. 1, 2-dibromoethane is used as an anti-knock agent to raise the octane number of gasoline and allow engines to run more smoothly.

Why is bromine having higher boiling point than fluorine?
Because.
The reason for this is that the physical attractive energy between bromine molecules is greater than that between fluorine molecules. The attraction between the molecules has to be overcome when boiling takes place. The type of attraction, in this case, is the Van der Waals attraction, being higher for bromine molecules because bromine molecules are much bigger, therefore having stronger transient dipoles (fluctuating dipoles due to the mobility of the electron density around the molecules).

No! The correct answer is mercury because it is only a metal that is liquid, bromine is not liquid.
