all right, so we know that our material is hard solid, so that means that it has strong molecular bonds. However, we also know that it doesn't conduct electricity either as a melt or as a solid. So that means that we know that we don't have an electron, see, So it's not a metal because metals conduct electricity of solids. And we know that is not an ionic solid, because ionic solids conduct electricity as melt. That leaves us with a cuvee inland nonmetal solvent surveillance solid.
