Question

The maximum number of electrons that can be accommodated in the $L$ orbit is ___

• A. 4
• B. 6
• C. 8
• D. 10

Answer 1

The correct option is C

8

The maximum number of electrons present in a shell is given by the formula $2n^2$, where ‘n’ is the orbit number or energy level index, 1,2,3,….
Hence the maximum number of electrons in different shells are as follows:

-first orbit or K-shell will be = $2\times 1^2=2,$

-second orbit or L-shell will be = $2\times 2^2=8,$

-third orbit or M-shell will be = $2\times 3^2=18,$

-fourth orbit or N-shell will be = $2\times 4^2=32,$ and so on.
