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

Brief Explanations:

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})
