the metal in liquid state at room temperature is mercury .bromine is also in liquid state but it is a non-metal. Mercury is the only metal element that is liquid at standard temperature and pressure. In very warm places without artificial cooling, gallium, which has a melting point just below 30C, could also be liquid at "room temperature".

Transition elements are ALL solid metals except for mercury (80Hg) which is a liquid.
80Hg(202) has 80 p + 122 n79Au(197) has 79 p + 118 nThis is 1 proton and 4 neutrons less than in Hg
