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 ...

Ionic compounds are also known as electrovalent compounds. The chemical bond formed by the transfer of electrons from one atom to another is known as Ionic bond. These compounds contain ions. Through ...

A small piece of sodium metal is placed in a flask of chlorine gas. 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 ...
