In the ground state of `Cu^(+)`, the number of shells occupied, şubshells occupied, filled orbitals and unpaired electrons respectively are

Options

A. 4, 8, 15, 0
B. 3, 6, 15, 1
C. 3, 6, 14, 0
D. 4, 7, 14, 2

Answer

C

Explanation

`Cu=1s^(2)2s^(2)3p^(6)3s^(2)3p^(6)3d^(10)`
Shells occupied =3, sub-shell occupied -6, filled orbitals =-14, Unpaired `e^(-)=0`
