Chemistry is a subdiscipline of science that deals with the study of matter and the substances that constitute it. It also deals with the properties of these substances and the reactions undergone by them to form new substances. Chemistry primarily focuses on atoms, ions, and molecules which, in turn, make up elements and compounds. These chemical species tend to interact with each other through chemical bonds. It is important to note that the interactions between matter and energy are also studied in the field of chemistry.The study of elements and compounds’ properties, compositions, and structures, as well as how they can change and the energy that is released or absorbed during such changes, is the subject matter of the science known as chemistry.
