Detailed explanation-1: -Water as a Compound and Molecule The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It’s also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other.

Detailed explanation-2: -It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect). In 1811 the Italian physician Amedeo Avogadro finally found the H2O formula for water.

Detailed explanation-3: -Meaning of H2O in English the chemical symbol for water; used to refer to the substance water: H2O means that each water molecule contains one oxygen and two hydrogen atoms.

Detailed explanation-4: -The chemical formula of water is H2O, as it has 2 hydrogen atoms and 1 oxygen atom. So, the chemical name of water is dihydrogen oxide.
