How can the octet rule be used to explain why one magnesium (mg) atom would bond with one oxygen (o) atom?

a. oxygen has six valence electrons; it needs to lose these electrons to reach the octet rule with a full second energy orbital. magnesium has two valance electrons; it would prefer to gain six valence electrons to reach the octet rule of a full second energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.

b. magnesium has six valence electrons; it needs to gain two electrons to reach the octet rule with a full second energy orbital. oxygen has two valance electrons; it would prefer to lose both valence electrons to reach the octet rule of a full second energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.

c. oxygen has one valence electron; it needs to gain two electrons to reach the octet rule with a full first energy orbital. magnesium has one valance electron; it would prefer to lose its valence electron to reach the octet rule of a full first energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.
