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 ...

These models usually use coloured balls to represent the ions. Some use sticks to show the ionic bonds. A 3D construction model still has limitations: A 3D model may be drawn as a 3D diagram.

the metal atoms give electrons to the non-metal atoms. The metal atoms become positive ions and the non-metal atoms become negative ions.
