Question

explain transition metals form number of complex compounds

Answer 1

Transition elements have tendency to form complexes more than s and p block elements, which form only a few complexes.

The reason is

1. They have small , highly charged ions.

2. They have vacant low energy orbitals to accept lone pairs of electrons donated by other groups or ligand .

So they are able to form complexes with the groups which are able to donate an electron pair .
These groups are known as ligands
