if mercury is in liquid state, how can it be classified as metals?

Expert Answer:

 Mercury has an exceptionally low melting temperature for a d-block metal.The absence of a filled inner f shell is the reason for the much higher melting temperature of mercury. mercury has a unique electronic configuration where electrons fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d and 6s subshells. As such configuration strongly resists removal of an electron, mercury behaves similarly to noble gas elements, which form weak bonds and thus easily melting solids.
