Question

2 the orbital diagram for a ground state nitrogen atom is: * (0.5 points) a b c d

Explanation:

Step1: Determine nitrogen's electron - configuration

Nitrogen has an atomic number of 7, so its electron - configuration is $1s^{2}2s^{2}2p^{3}$.

Step2: Apply Hund's rule for 2p orbitals

According to Hund's rule, electrons in degenerate orbitals (2p orbitals here) will occupy separate orbitals with parallel spins before pairing up. In the 1s and 2s orbitals, there are 2 electrons each with opposite spins. In the 2p orbitals, the 3 electrons will occupy 3 separate 2p orbitals with the same spin.

Answer:

A. $\uparrow\downarrow$ (1s), $\uparrow\downarrow$ (2s), $\uparrow$ $\uparrow$ $\uparrow$ (2p)
