∙ 7y agoH2O means two atoms of hydrogen combine with one atom of oxygen to make one molecule of water. The H stands for hydrogen and the subscript 2 of the H indicates that there are two atoms of hydrogen. The O is the symbol for an oxygen atom. This means that 2 hydrogen atoms and one oxygen atom bond, or join together, to form water
The chemical formula H2O is the formula of water.
