Explain the formation of $H_{2}$ molecule on the basis of Valence Bond Theory.

What change occurs in the electronic configuration of atoms forming a covalent bond?

What different types of bonds are formed by chlorine with oxygen in perchloric acid $(HClO_4)$?

The bond dissociation energy of $B-F$ in $BF_3$ is $646 \ kJ \ mol^{-1}$ whereas that of $C-F$ in $CF_4$ is $515 \ kJ \ mol^{-1}.$ The correct reason for higher $B-F$ bond dissociation energy as compared to that of $C-F$ is
