Product Name Sodium chloride.Neither MgO , nor NaCl are molecular species, and they are both extended arrays of anions and cations close-packed together in an ionic lattice. MgO has a higher melting point than NaCl because 2 electrons are transferred from magnesium to oxygen to form MgO while only 1 electron is transferred from sodium to chlorine to form NaCl. Properties. Sodium chloride, NaCl. High melting point: 800C. Non-conductive in its solid state, but when dissolved in water or moltenmolten: Molten means reduced to liquid form by heating.Magnesium oxide, MgO. Question: Why would MgO have a higher melting point than NaCl? NaCl , Mgo , AlF3 , NaBr Rank from lowest to highest lattice energy.?NaCl, for example, melts as we saw, is also reflected in the lattice energy.Of KCl and NaCl, which has a higher lattice energy? Why is the boiling point of NaCl higher than that of MgCl2? As with boiling points, the melting point of a solid is dependent on the strength of those attractive forces.
