For example, MgI2 has a electronegativity difference of 1.3 (which is smaller than 1.67, the rule to be a covalent bond). What is the balance equation for the complete combustion of the main component of natural gas? H2S - covalent 4. 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. The two valence electrons of Mg will be distributed to each of the Iodine atoms. The need for the number of electrons lost being equal to the number of electrons gained explains why ionic compounds have the ratio of cations to anions that they do. So when determining if a molecule is ionic or covalent, it is not always/only dependent on the electronegativity difference?
