1.	To what extend do the electronic configuration decide the stability of oxidation state in the first series of the transition elements? Illustrate your answer with an example.
Answer» In a transition series, the oxidation state which lead to exactly half filled or completely filled is [Ar] 3d⁶ ,4s² orbitals are more stable. e.g. the electronic configuration of Fe. It shows various oxidation state but Fe(III) is more stable than Fe(II).

In a transition series, the oxidation state which lead to exactly half filled or completely filled is [Ar] 3d⁶ ,4s² orbitals are more stable.

e.g. the electronic configuration of Fe. It shows various oxidation state but Fe(III) is more stable than Fe(II).
