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 valence shell for stability. Sodium (Na) has an atomic number of 11. Its electron configuration is 2 - 8 - 1. In the given diagram, the valence shell (outermost shell) has only 1 electron, not 8.

Answer:

No, this atom does not satisfy the octet rule. Sodium's valence shell has 1 electron (needs 8 for the octet rule).
