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

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

Hector is incorrect. The two ions have more than eighteen protons, so they will bond together in a binary 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.
