Q. In the ground state of $Cu^{+}$, the number of shell occupied, sub-shells occupied, fillied orbitals and unpaired electrons respectively are
A) 4,8,15,0
B) 3,6,15,1
C) 3,6,14,0
D) 4,7,14,2
Explanation
(c)
$\ _{29}Cu = 1s^{2},2s^{2},2p^{6},3s^{2},3p^{6},4s^{1},3d^{10}$
$Cu^{+} = 1s^{2},2s^{2},2p^{6},3s^{2},3p^{6},3d^{10},4s^{0}$
Total number of shells occupied $= 3$
Number of sub-shell occupied = 6
Number of orbitals filled $= 14$
Number of unpaired electrons = 0
