In some respects, ions of a given d
n configuration
(n = 1 – 9) have similar magnetic and electronic properties With partly
filled d orbitals these elements exhibit certain characteristic properties
such as display of a variety of oxidation states, formation of coloured
ions and entering into complex formation with a variety of ligands The transition metals and their compounds also exhibit catalytic
property and paramagnetic behaviour All these characteristics have
been discussed in detail later in this Unit
