Answer 1

Bromine and mercury( Br & Hg) are liquid at room temperature.

there are 4 other elements which melt few degrees above room temperature. they are Francium,Caesium,Gallium and Rubidium.

Gallium a brittle solid at low temperatures, and a liquid at temperatures greater than 29.76 °C (85.57 °F) (slightly above room temperature). The melting point of gallium is used as a temperature reference point.

Thus gallium is liquid at room temperature.
