Magnesium is a metal and chlorine is a non-metal. Therefore magnesium chloride is held together by ionic bonding (metal + non-metal). Structure is a giant ionic lattice. It has a high melting ...

Calcium becomes a +2 ion and each chlorine becomes a -1 ion. The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic bond and the compound calcium chloride. One calcium ...

They form ions which bond to form sodium chloride ... diagrams for the formation of ions in some ionic compounds – magnesium oxide and calcium chloride.
