Expert Solution

Rules for electron filling in orbitals:

1. Aufbau’s principle: According to this principle, the lower energy orbital will be filled before the higher energy orbital. Hence, the order of electron filling will be:

1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < and so on

2. Hund’s rule: According to this rule, before pairing electrons in orbitals of a subshell, each orbital should be filled with one electron. The pairing of electrons will occur once all orbitals of a subshell receive a single electron. Example:

Orbitals	px	py	pz
Electrons(=2)	↑	↑

Orbitals	px	py	pz
Electrons(=3)	↑	↑	↑

Orbitals	px	py	pz
Electrons(=4)	↑↓	↑	↑

3. Pauli Exclusion Principle: According to this principle, two electrons cannot occupy the same orbital with the same spin.

Example:

↑↓	This is allowed
↑↑	This is NOT allowed
