If you have. Therefore applying these definitions : H2SO4 = molecular , acid HI = molecular, acid iron (III) sulfide iron (II) sulfide. Magnesium iodide is a salt of magnesium and hydrogen iodide. Some people may find it easier to take supplements first thing in the morning, while others may find it easier to take them with dinner or just before bed. For ionic bonds the covalent character can be determined by polarizing power and polarizability but even then those originate from the atom's electronegativity in the first place so I'm not too sure if there is anything but knowing trends in electronegativity that apply to the character of a bond. Chemical formulaMgI 2 (anhydrous) Molar mass278.1139 g/mol (anhydrous) Appearancewhite crystalline solid Odorodorless Density4.43 g/cm3 (anhydrous solid) If you were to compare a group I element against Al then group I would make an ionic.
