Hector claims that a single sodium ion and a single oxygen ion do not bond together to form a stable ionic compound. Is he correct? Why or why not?

Hector is incorrect. The two ions have opposite charges, so they will bond together in an ionic compound.

Hector is incorrect. The two ions have more than eighteen protons, so they will bond together in an ionic compound.

Hector is correct. The sum of the charges of the two ions must be zero in order for them to form a stable ionic compound.

Hector is correct. The sum of the protons of the two ions must be divisible by eight in order for them to form a stable ionic compound.
