Sodium Chloride is an alkali halide with an fcc crystal structure ... The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b) of ionic hard spheres. The ...

Tell students that each salt crystal is made up of two different types of particles called sodium ions and chloride ions. Tell students that ions are atoms or molecules that have either a positive or ...

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 reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

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 ...
