Question

.) Which of the following rules is not used to determine the electronic configuration and Why?
(a) Pauli's (b) Saytzeff
(c) Hund's (d) Aufbau​

Answer 1

Answer:

That is, we follow the three important rules: Aufbau's Principle, Pauli-exclusion principle, and Hund's Rule. The electronic configuration of cations is assigned by removing electrons first in the outermost p orbital, followed by the s orbital and finally the d orbitals (if any more electrons need to be removed).
