Question

The maximum number of electrons in a subshell is given by the expression

• A. 4l -2
• B. 4l + 2
• C. 2l + 2
• D. $2n^2$

Answer 1

Answer: (B)

4l + 2

Answer 2

The number of orbitals in a subshell = (2l + 1)
where, l = azimuthal quantum number
Since, each orbital contains maximum two electrons, the number of electrons in any subshell
= 2 $\times$ number of orbitals
= 2 (2l + 1)
= 4l + 2
