Fill in the blank: If an atom is in column V (or 15), it will most likely to fulfill the octet rule. Gain 3 electrons

Lose 5 electrons

Gain 5 electrons

Lose 5 protons

Gain 3 protons

If an atom is in column V (or 15), it will most likely gain 3 electrons to fulfill the octet rule.

Explanation:

The octet rule defines the property that atoms have to complete their last energy level with eight electrons to achieve stability through an ionic, covalent or metallic bond.

The pair of electrons that are transferred or gained belong to the last shell of the atom. If an atom is in column V (or 15), it means that it has 5 electrons in its last shell. So an atom in this group is more likely to gain 3 electrons to achieve stability than to lose the 5 electrons it has.
