In the ground state of Cu^ + , the number of shells occupied,...

In the ground state of Cu+\mathrm{Cu}^{+}, the number of shells occupied, subshells occupied, filled orbitals and unpaired electrons respectively are

Options

  1. A4,8,15,04,8,15,0
  2. B3,6,15,13,6,15,1
  3. C3,6,14,03,6,14,0
  4. D4,7,14,24,7,14,2

Correct answer

C. 3,6,14,03,6,14,0

Step-by-step solution

Cu+=1s22s22p63s23p63d10\mathrm{Cu}^{+}=1 s^2 2 s^2 2 p^6 3 s^2 3 p^6 3 d^{10}. Shells occupied =3=3, sub-shells occupied =6=6, filled orbitals =14=14. Unpaired e−=0e^{-}=0.
