Q. Assertion :The electronic configurations in which all of the orbitals of the same subshell are either completely filled or are exactly half filled are more stable. Reason: The completely filled or exactly half filled shells possess a symmetrical distribution of electrons and allow their maximum number of exchanges.

Q. Assertion :The ground state of configuration of

3 d^{5} 4 s^{1}

. Reason: A set of half-filled orbitals containing one electrons each with their spin parallel provides extra stability.
