A 3D construction model shows how the ions are arranged in a lattice structure. These models usually use coloured balls to represent the ions. Some use sticks to show the ionic bonds. A 3D ...

Dot and cross diagrams help us to model when ions ... Here are some other examples of dot and cross diagrams for the formation of ions in some ionic compounds – magnesium oxide and calcium ...

A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...
