What is maximum number of electrons accommodated in a subshell having azimuthal quantum number, $\ell=2$ ?
  1. 10
  2. 12
  3. 14
  4. 18

Solution

The Azimuthal quantum number $(\mathrm{l}=2)$ corresponds to $\mathrm{d}$-subshell and d-subshell has 5-orbitals, which can accommodate a maximum of 10 electrons.
