Interpretation:
The electronic configuration of
Concept introduction:
The filling of the electrons in the orbital can be done by the three sets of the principle are as follows:
(a). The Afbau principle:- This principle is stated that the lower energy of the orbital would be assigned electrons before the higher energy of the orbital.
(b). The Hund’s rule:-According to this rule, the pairing of the electrons can be done in the subshell after each of the subshells has a single electron.
(c). The Pauli’s exclusion principle:-This principle is stated that both electrons are present in either positive half-spin or negative half spin.
Answer to Problem 21.1P
The electronic configuration of
