lithium only has one valence electron. it really wants to get rid of that valence electron. halogens such as the pictured fluorine, chlorine, bromine, and iodine have seven valence electrons. they really want to obtain one more valence electron to form a stable outer shell. thus, the lithium donates its electron, forming an ionic compound
