Explanation: First two are covalent -HCN, ClF. Ionic bonds are formed when an electron moves from one atom to another, and covalent bonds are formed when two different atoms share one or more pair of electrons. The simplest explanation is that MgI2 is ionic, because Mg is an alkali metal, which reacts by losing elkectrons, and I is a halogen, which reacts by gaining them. Magnesium iodide is actually pretty borderline between ionic and covalent. Ionic bonds form instead of covalent bonds when there is a large difference in electronegativity between the ions. 26.
