Problem: Write the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by Na.

FREE Expert Solution

To answer this problem, first we need to know the total number of electrons in a neutral Na. Recall that in a neutral atom:

atomic number = # of protons = # of electrons

Atomic number of Na = 11  → # of electrons

When writing electron configuration:
