Question

How many electrons are there in the L-shell?

• A. 2
• B. 8
• C. 18
• D. 36

Answer 1

Answer: (B)

8

Maximum number of electrons in a shell is '$2n^2$', where '$n$' is the principal quantum number.
For $L$ shell, the principal quantum number is '$2$'.
So, the number of electrons will be $2(2{)}^2$ which corresponds to $8$ electrons.
Hence, option $B$ is the correct answer.
