Chromium is a typical hard metal while mercury is a liquid. Explain wh – InterviewSolution

1.	Chromium is a typical hard metal while mercury is a liquid. Explain why ?
Answer» SOLUTION :Cr has five unpaired d electrons in the d-subshell `( 3d^(5) 4S^(1))` . HENCE, metallic BONDS are very strong. In Hg, all the d-orbitals are fully filled `( 3d^(10) 4s^(2))`. Hence, the metallic bonding is very weak.
