Question Analysis
This question assesses the student's understanding of Hund’s rule and its application to the 2p sublevel of a nitrogen atom.

Key Concept Explanation
Hund’s rule states that in degenerate orbitals (e.g., p³), electrons occupy separate orbitals with parallel spins first. Nitrogen has 7 electrons, and the 2p sublevel contains 3 electrons.

Step-by-step Solution
1. Determine the number of 2p electrons in nitrogen: 3.
2. Apply Hund’s rule: Place one electron in each of the three 2p orbitals with parallel spins.
3. The correct orb...
