WebAn element is a pure substance consisting of only one type of atom which all have the same numbers of protons in their nuclei. The question of the conceptual nature of the term “element” represents a rather unique opportunity to examine the relationship that currently exists between chemists and philosophers of chemistry. WebBased on its composition, matter can be classified into two groups — pure substances and mixtures. By definition, a matter is said to be pure if it is made of only one component, with a uniform composition throughout. For example, take helium. Helium is made up of only helium atoms. Similarly, water is made of only water molecules.

WebClassification of Matter. Matter can be placed into two classes: pure substances and mixtures. This classification is based on the internal composition of that matter.
