(c)Magnesium nitride is also an ionic compound. Draw a dot-and-cross diagram which shows its formula, the charges on the ions and the arrangement of the valence
electrons around the negative ion.
Use x to represent an electron from a magnesium atom.
Use o to represent an electron from a nitrogen atom.
