If the electronic configuration of Nitrogen atom is represented as shown above, then which of the following rules have been violated?
If the electronic configuration of Nitrogen atom is represented as shown above, then which of the following rules have been violated?
The correct options are
C Hund's rule
D Pauli's exclusion principle
A) According to Aufbau principle, electrons fill orbitals starting at the lowest available (possible) energy levels before filling higher levels (e.g. 1s before 2s).
B) Pauli's exclusion principle can be stated as follows: It is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers (n,l,ml and ms). For two electrons residing in the same orbital, if n, l, and ml are the same, then ms must be different and the electrons have opposite spins.
C) According to Hund's rule, if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.
