Question

explaining the octet rule
sample response: no, it does not, because the octet rule says that an atom needs to have eight electrons in its valence shell to be stable. the exceptions are hydrogen and helium, which need only two electrons. this atom has only one electron.
what did you include in your response? check all that apply.

• the octet rule says that atoms need to have eight electrons to be stable, except for hydrogen and helium, which need only two electrons.
• this atom has only one electron, so it does not satisfy the octet rule.

Explanation:

The sample response includes two key points: the definition of the octet rule with exceptions (hydrogen and helium needing 2 electrons) and the atom having only one electron. Both options match these points.

Answer:

The octet rule says that atoms need to have eight electrons to be stable, except for hydrogen and helium, which need only two electrons.
This atom has only one electron, so it does not satisfy the octet rule.
