Why is  the maximum covalency of first elements of each group  in the p block is 4?

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.
