Which of the following statements is correct?

Options

A. Total number of electrons in a subshell is `2l+1`.
B. `p_(z), d_(x^(2)-y^(2))` and `d_(z^(2))` orbitals are non-axial
C. Only s orbital has directional orientation while `p_(z)` d and f orbitals have non-directional properties.
D. Spin multiplicity of nitrogen atom is 4.

Answer

D

Explanation

Nitrogen has 3 unpaired electrons, therefore, `S=3xx(1)/(2)=(3)/(2)`.
Spin multiplicity of nitrogen atom : `2S+1= (2xx(3)/(2))+1=4`
