ScCl3 MgI2 PbS CuSe. 5. Ionic Character has more to do with Electronegativity because the greater the difference in electronegativity the more similar the covalent bond is to an ionic one because the charges are distributed unevenly to a greater degree. MgI2. Since magnesium oxide accepts protons (H^+ ions), it is a base (as per Bronsted-Lowry definition of acids and bases). DETERMINE WHETHER EACH SUBSTANCE BELOW IS IONIC, MOLECULAR OR AN ACID. Aqueous solution of magnesium sulfate is going to be slightly acidic, and there is no need to even go to the lab to test it. Covalent Character has more to do with Polarizability which relates to atomic and Ionic radius. A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. Heteronuclear atoms with an electronegativity difference: I'm pretty sure determining this revolves around electronegativity. NH4CIO2 has a weak base and a strong acid, therefore it is a weakly acidic solution. Explanation: MgCl2 is a generally considered to be a neutral salt. It is odourless and is highly soluble in water.
