All matter can be classified into two categories: pure substances and mixtures. A pure substance consists of elements or compounds.Elements are the simplest substances in nature and a compound is formed when two or more elements chemically combined together. The components of a compound lose their individual properties and the properties of a compound are different from their individual components. A mixture is a combination of two or more substances which are not chemically the same. In a mixture, the components are present in any proportion and they can be identified visually within the mixture. The properties of a mixture are the same as the properties of individual compounds.
