All substances are made up from tiny particles called atoms. When a substance is made up of only one type of atom it is called an element. The element iron is made up of iron atoms, the element hydrogen is made up of hydrogen atoms, the element sulphur is made up of sulphur atoms and so on.. Pure substances cannot be broken down by physical means.. Pure substances . contain . only one kind of molecule.. Molecules are small groups of atoms that make up matter. Example: Water is a molecule of two hydrogen atoms, and one oxygen atom. How can matter be classified?. Atoms . are the smallest unit of an element that maintains the properties of that element..
