Question

which of the following electron configurations is correct for nitrogen? a) 1s22s22p3 b) 1s22s22p1 c) 1s22s22p63s2 d) 1s22s22p5

Explanation:

Nitrogen has an atomic number of 7. The electron - filling order is 1s, 2s, 2p. The 1s orbital can hold 2 electrons, the 2s orbital can hold 2 electrons, and the remaining 3 electrons go into the 2p orbital. So the electron configuration of nitrogen is \(1s^{2}2s^{2}2p^{3}\).

Answer:

A. \(1s^{2}2s^{2}2p^{3}\)
