Question

why bromine and mercury liquid at room temperature​

Answer 1

★Bromine is a liquid because the intermolecular forces are strong enough so that it does not vapourise. Br forms diatomic molecules and van der Waals interactions are sufficiently strong. ... Mercury and bromine are two elements which exists as liquid at room temperature.

Answer 2

Answer:

Mercury has a special electron configuration that means the bonds between the mercury atoms are much weaker than the bonds of other metals, so it's liquid at room temperature instead of solid. Bromine just happens to have a boiling point above room temperature - it's not unusual for its group, or anything.
