Answer: The electron configuration of nitrogen (N) is 1s22s22p3.
Explanation:
When electrons of an atom are distributed in a molecular orbital then this distribution is known as electronic configuration.
Atomic number of nitrogen is 7 and its electronic distribution is 2, 5.
Whereas the electronic configuration of nitrogen is as follows.
[tex]1s^{2}2s^{2}2p^{3}[/tex]
Thus, we can conclude that out of the given options only option (A) depicts correct electron configuration of nitrogen (N).
