An Ionic bond is formed when one of the atoms can donate electrons to achieve the inert gas electron configuration and the other atom needs electrons to achieve the inert gas electron configuration.

Dot and cross diagrams help us to model when ions are formed from atoms. Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons ...

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.
