All materials are made of elements. Some are made of one element only. Gold rings are made from gold.
Gold is an element.
Some materials are made of more than one element combined together. When sodium and chlorine combine together they form white crystals of sodium chloride, known as common salt. There are about 100 elements all together. Other examples of elements are hydrogen, copper, oxygen and iron. All materials, whether they contain one element or more than one element are made up of very small particles called atoms.
