Electron configuration of nitrogen (Z = 7):
A2s² 2p⁵
B1s² 2s² 2p⁴ 3p¹
C1s² 2s² 2p³
D1s² 2s² 2p² 3s¹
Answer & Solution
Correct answer: C. 1s² 2s² 2p³
N has 7 electrons: 1s² 2s² 2p³. The 2p³ has 3 unpaired electrons by Hund's rule (each in a separate p-orbital). Very stable half-filled state, contributing to N's special inertness.
