Question

consider the model of the nitrogen atom. which electron configuration matches this model? ( 1s^2 2s^2 2p^2 ) ( 1s^2 2s^2 2p^3 ) ( 1s^2 2s^2 2p^4 ) ( 1s^2 2s^2 2p^5 ) save and exit next submit mark this and return

Explanation:

1. First, recall that the atomic number of nitrogen is 7 (since protons, P = 7). The electron configuration is determined by filling orbitals: 1s (holds 2), 2s (holds 2), then 2p.
2. Calculate total electrons: 7. For \(1s^2 2s^2 2p^x\), \(2 + 2 + x = 7\) → \(x = 3\). So the configuration is \(1s^2 2s^2 2p^3\).

Answer:

\(1s^2 2s^2 2p^3\) (the second option: \(1s^2 2s^2 2p^3\))
