In the ground state of $\mathrm{Cu}^{+}$, the number of shells occupied, subshells occupied, filled orbitals and unpaired electrons respectively are
  1. $4,8,15,0$
  2. $3,6,15,1$
  3. $3,6,14,0$
  4. $4,7,14,2$

Solution

$\mathrm{Cu}^{+}=1 s^2 2 s^2 2 p^6 3 s^2 3 p^6 3 d^{10}$. Shells occupied $=3$, sub-shells occupied $=6$, filled orbitals $=14$. Unpaired $e^{-}=0$.
