1 Ionic bonding results in compounds known as ionic, or electrovalent, compounds, which are best exemplified by the compounds formed between nonmetals and the alkali and alkaline-earth metals.
Ionic compounds typically have much higher melting points than molecular compounds. Ionic compounds are held together by electric attractions between positive and negative ions. These are ionic bonds, and these bonds keep the ions together in a regular 3-d pattern (a crystal lattice) To melt an ionic substance, you have to disrupt these bonds. This requires a lot of energy.
