Question #2c09c

Answer 1

The number of valence electrons will determine the number of ions that one ion needs to combine with to form a neutral ionic compound.

Explanation:

The number of valence electrons will determine the number of ions that one ion needs to combine with to form a neutral ionic compound.

For example, Aluminum `Al` has three valence electrons to lose to form `Al^(3+)`.

Chlorine `Cl` has 7 valence electrons, and it can gain one more electron to obey the octet rule and it will form `Cl^-`.

To form a neutral ionic compound, one ion `Al^(3+)` will combine with three ions `Cl^-` to form aluminum chloride `AlCl_3`
