Question

The maximum number of electrons that can be accomodated in the L shell is:

• A. 2
• B. 8
• C. 18
• D. 32

Answer 1

The correct option is B

8

A shell of an atom can have maximum of ${\text{2n}}^2$, where 'n' is the shell number. L-shell is the ${\text{2}}^{\text{nd}}$ shell, which means n=2.
$\therefore {\text{2x(2)}}^2=8$
Hence, the L-shell can accomodate maximum of 8 electrons.
