The properties of ionic compounds include: high melting point, high boiling point, conductive in liquids, soluble in all nitrates and most sulfates, chlorides, bromides, and iodides. Ionic and covalent compounds differ in their properties because the particles in each of these two compounds are held together by different types of chemical bonds. Both types of bonding result in atoms becoming more stable in the group than they were individually. Inorganic solids often have simple crystal structures, and some of these structures are adopted by large families of ionic or covalent compounds.
