Expert Answer:
First elements of each group in the p-block elements shows anomalous behaviour due to:
- Small size
- High electronegativity
- Non-availability of empty d-orbitals
Due to these reasons, compounds of the first elements of each group are highly covalent and show maximum covalency of four.
