Question Analysis
This question evaluates the student's ability to write the electron configuration for an element using the Aufbau principle.

Key Concept Explanation
The Aufbau principle states that electrons fill the lowest-energy orbitals first. Neon (atomic number 10) has 10 electrons, which fill the 1s, 2s, and 2p orbitals.

Step-by-step Solution
1. Identify the atomic number of neon: 10.
2. Apply the Aufbau principle: 1s (2 electrons) → 2s (2 electrons) → 2p (remaining 6 electrons).
3. Write the el...
