Question

multiple choice question
the outer energy level of oxygen is stable with ______ electrons.
o 2
o 6
o 8

Explanation:

The octet rule states that atoms tend to gain, lose, or share electrons to have 8 electrons in their outer - shell for stability. Oxygen has 6 valence electrons and needs 2 more to complete its outer shell. But the question is about the stable number of electrons in the outer energy level (based on the octet rule concept).

Answer:

8
