Question Analysis
This question evaluates the student's ability to write the complete electron configuration of an element.

Key Concept Explanation
Sulfur has 16 electrons. The electron configuration must follow the Aufbau principle, Pauli exclusion principle, and Hund’s rule.

Step-by-step Solution
1. Total electrons: Neutral S atom has atomic number = 16 = 16 electrons.
2. Fill orbitals in energy order:
1s (2 electrons): 1s²
2s (2 electrons): 2s²
2p (6 electrons, maximum capacity): 2p⁶
3s (2 electrons): 3s²
Remaining 4 elec...
