Question

how many valence electrons does nitrogen have?

Explanation:

Nitrogen has an atomic number of 7. Its electron configuration is \(1s^{2}2s^{2}2p^{3}\). The valence electrons are in the outermost shell (n = 2). The sum of electrons in the n = 2 shell (\(2s^{2}+2p^{3}\)) gives the number of valence electrons.

Answer:
