Question Analysis
This question involves determining atomic number from electron configuration.
The main focus is on summing the superscripts in the electron configuration to find the total number of electrons, which equals the atomic number for a neutral atom.

Key Concept Explanation
Neutral Atom Electron Count: For a neutral atom, the number of electrons = atomic number. The superscripts in an electron configuration represent the number of electrons in each subshell; their sum is the total number of electrons.

Step-by-Step Solution
1. Identify the superscripts in the given configuration: 2 (1s) + 2 (2s) + 6 (2p) + 2 (3s) + 1 (3p).
2. Sum the superscripts: 2 +...
