• C. N N P N
• D. C C C C

Answer 1

Answer: (B)

N N N N

$\left(i\right)$ Radii of $2^{nd}$ period is less than $3^{rd}$ period$.$

$\left(ii\right)$ Half-filled atomic orbitals $($less size$)$ is having more $IE.$

$\left(iii\right)$ Half-filled orbital has least tendency to accept electron$.$

$\left(iv\right)$ Nitrogen is most electronegative due to smallest radii$.$
