Question

The maximum no. of electrons in a shell can be given by the formula $2n^2$

Calculate the maximum no. of electrons in the 'N shell'.

• A. 4
• B. 16
• C. 32
• D. 64

Answer 1

The correct option is C 32

$4^{th}$ shell represent N shell. By the formula $2n^2$ value of n is four.

Hence, $2n^2$ $=$ $2\times 4^2$ $=$ 32 electrons.
