halogens are nonmetallic and generally react by gaining one electron per atom to
attain a noble gas electron configuration and an oxidation state of 1. Halides are
positive. If energy is required to form both positively charged ions and monatomic
polyanions, why do ionic compounds such as MgO, Na2S, and Na3P form at all?
The key factor in the formation of stable ionic compounds is the favorable
