Question

The maximum number of electrons that can be filled in the shells K, L, M and N respectively are:

• A. 2, 8, 18, 32
• B. 2, 8, 8, 16
• C. 2, 8, 8, 32
• D. 2, 8, 16, 32

Answer 1

The correct option is A

2, 8, 18, 32

The maximum number of electrons that can be accommodated in any shell according to Bohr and bury is 2 $\times$ $n^2$, where n is the shell number

K-Shell will be=$2$ $\times$ $1^2$=$2$

L- Shell will be=$2$ $\times$ $2^2$ = $8$

M- Shell will be= $2$ $\times$ $3^2$ =$18$

N- Shell will be= $2$ $\times$ $4^2$= $32$

The maximum number of electrons that can be filled in the shell K, L, M, N respectively are 2, 8, 18, 32.
