What is a Compound? Definition, Examples, and Properties

A compound is a substance that is composed of two or more different elements that are chemically bonded together. In other words, a compound is a chemical substance that is made up of two or more different chemical elements that are combined in a fixed ratio, and the properties of the compound are different from the individual elements.

For example, water (H2O) is a compound made up of hydrogen and oxygen atoms, and the properties of water are different from those of hydrogen and oxygen alone. Similarly, salt (NaCl) is a compound made up of sodium and chlorine atoms, and the properties of salt are different from those of sodium and chlorine alone.

Compounds can be found in all sorts of materials, including living organisms, minerals, and man-made substances. They are an important part of chemistry and are used in many different applications, such as in medicine, agriculture, and industry.
