The chemical bond formed by the transfer of electrons from one atom to another is called ionic bond. It is also known as electrovalent bond. And the compounds containing ionic bonds are called ionic ...

A dot and cross diagram for sodium chloride suggests that it is made up of pairs of sodium and chloride ions. It is not. A 3D construction model shows how the ions are arranged in a lattice structure.

The details of how ions are formed are not required for this topic. In Unit 1 you are expected to be able to use the table of common ions to identify the ions present in a compound and then construct ...
