What happens when aluminum fills its valence shell? a. three electrons are lost, creating al ^ +3 b. three electrons are gained, creating al ^ -3 c. three electrons are gained, creating al ^ +3 d. three electrons are lost, creating al ^ -3

Correct answer is B. Three electrons are gained, creating Al ^ -3

Explanation:

Aluminum in its valence shell has 3 electrons, this shell can have a maximun of 6 electrons. Then, to fill its valence shell, 3 electrons must be gained, and then the valence shell would have 6 electrons and would be complete.

If 3 electrons are gained, then Aluminum, would have a charge of -3, since each electron gained gives negative charge to the atom.

Al^ -3  is a ion of aluminum with charge -3.
