Question

what does the octet rule state that explains why atoms bond?
an atom bonds to have eight valence electrons to become stable.
an atom bonds to lose eight valence electrons to become stable.
an atom bonds to have eight valence electrons to become unstable.
an atom bonds to lose eight valence electrons to become unstable.

Explanation:

The octet rule states that atoms tend to bond in such a way that they achieve a stable electron configuration with eight valence electrons (similar to the noble gases). So an atom bonds to have eight valence electrons to become stable. The other options are incorrect: losing eight valence electrons is not the goal (and is not typical as losing eight would be very difficult for most atoms), and bonding to become unstable goes against the purpose of bonding (which is to achieve stability).

Answer:

A. An atom bonds to have eight valence electrons to become stable.
