Explain how do the octect forms in cations and anions

Explanation:

-Octet forms when the valence electrons are gained, lost or shared.

-In order to become stable, which has 8 valence electrons (octet), nonmetal groups such as group 17, needs to gain 1 more electron to become 8/ octet.

When gaining that 1 electron, group 17 elements become negative ion or anions

-For metal groups such as group 1, they need to lose that 1 electron to become stable. When they lose that 1 electron, they become positive ion which is cation.

Hope this helps

the answer is c i believe
