What is the chemical makeup of water?

Water is a chemical compound composed of two hydrogen atoms bonded to one oxygen atom, and its chemical formula is H2O. This formula indicates that each water molecule consists of two hydrogen atoms and one oxygen atom. The hydrogen atoms are covalently bonded to the oxygen atom by sharing electrons, resulting in a stable and polar molecule. The chemical makeup of water as H2O reflects its unique properties, such as its high boiling point, ability to dissolve many substances, and crucial role in sustaining life on Earth.
