consider the model of the nitrogen atom. which electron configuration matches this model? 1s²2s²2p²…

Explanation:

Step1: Determine number of electrons

Nitrogen has atomic number 7, so it has 7 electrons.

Step2: Fill electron - shells

The first shell (1s) can hold 2 electrons, the second shell's 2s sub - shell can hold 2 electrons, and the remaining electrons go to the 2p sub - shell. So we have 2 electrons in 1s, 2 in 2s, and 3 in 2p.

Answer:

$1s^{2}2s^{2}2p^{3}$
