Hydrogen (H), and Oxygen (O). It is made up of two atoms of hydrogen and one atom of oxygen, therefore its molecular structure is written 'H2O'.
Water, with the chemical formula H2O, is composed from hydrogen and oxygen.
Hydrogen and Oxygen
The only elements in pure water are those of which water itself is comprised ...hydrogen and oxygen. In impure water, any other elements that are themselvessoluble in water, or that are components of water-soluble compounds, or that areground up fine enough to be physically suspended in water, can also be found.
the four elements were Earth, air, fire, and water.
