Question

does this atom satisfy the octet rule? why or why not?

Explanation:

The octet rule states that atoms tend to have 8 electrons in their outer - most shell for stability. Sodium (Na) has an atomic number of 11. Its electron configuration is 2, 8, 1. The outer - most shell has 1 electron, not 8.

Answer:

No, because sodium has 1 electron in its outermost shell instead of 8 as required by the octet rule.
