Question Analysis
This question involves electron configuration for noble gases. The main focus is on applying the Aufbau principle to fill orbitals up to the complete 2p subshell for an element with 10 electrons.

Key Concept Explanation
Noble Gas Configuration: Noble gases (Group 18) have fully filled valence electron shells, making their electron configurations stable. For Ne, the valence shell (n = 2) is filled with 2s²2p⁶.

Step-by-Step Solution
1. Neutral Ne has 10 electrons (atomic number = 10).
2. Fill orbitals in order: 1s² (2 e⁻) → 2s...
