It maybe because Cr has many unpaired electrons which helps in forming strong metallic bonds while Hg has no unpaired electrons so it does not show metallic bonds and liquifies at a lower temperature.

Answer: Chromium is hard metal while mercury is a liquid.

Explanation: Cr has five unpaired D-electrons in the d-subshell (3d5, 4s1) hence, metallic bonds are very strong. In Hg, all the d-orbitals are fully filled (3d10, 4s2) and hence, the metallic bonding is very weak.
