The maximum number of electrons that could be present in a shell is given by the rule 2n².

Where n is the shell number.

The first shell K shell can accommodate a maximum of 2 electrons ($2 \times 1^2 = 2$).

The second shell L shell can accommodate a maximum of 8 electrons ($2 \times 2^2 = 8$).

Likewise, the 4th shell named N can accommodate a maximum of 32 electrons ($2 \times 4^2 = 2 \times 16 = 32$).
