Elements :
An element is a substance that cannot be broken down into any other substance. Every element is made up of its own type of atom. This is why the chemical elements are all very different from each other.
Compounds :
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together. The elements in any compound are always present in fixed ratios. Example 1: Pure water is a compound made from two elements - hydrogen and oxygen.
Mixture :
A mixture is a substance which consist of two or more elements or compounds not chemically combined together. For Example Air is a mixture of gases like oxygen,nitrogen,argon,carbon dioxide etc. The various substance present in a mixture are called as its constituents or components.
