Which two elements make up water?

Water is a clear, colorless, and odorless liquid that is essential to life on earth. It is composed of two chemical elements: hydrogen and oxygen. Its chemical formula is H₂O, which means that each molecule of water contains two hydrogen atoms and one oxygen atom.

The hydrogen and oxygen atoms are held together by covalent bonds, which are strong chemical bonds that involve the sharing of electrons between atoms. Water molecules are attracted to each other through hydrogen bonds, which are weaker than covalent bonds, but still important in determining the properties of water.

The fact that water is made up of two very common elements, hydrogen and oxygen, makes it a very important and abundant compound on earth. It is essential for many processes in living organisms, and is also used in a wide range of industrial and commercial applications.
