Question

how many valence electrons should nitrogen, element #7, have around its lewis dot model?

Explanation:

Step1: Determine electron configuration

Nitrogen has atomic number \(7\). Its electron configuration is \(1s^{2}2s^{2}2p^{3}\).

Step2: Identify valence electrons

The valence shell is the second shell (\(n = 2\)). The number of electrons in \(2s^{2}2p^{3}\) is \(2 + 3=5\).

Answer:

\(5\)
