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 ... of dot and cross diagrams for the formation of ions in some ionic compounds – magnesium oxide and calcium chloride.

Ionic bonds are formed between a metal and non-metal, for example, sodium chloride. Outer electrons are transferred from the metal to the non-metal. Sodium will lose an electron and form a ...
