Water is comprised of only two elements: Hydrogen (H2) and Oxygen (O), hence why the formula is H2O. Oxygen makes up about 20-22% of the air we breathe. Nitrogen makes up about 70-75% of the air we breathe. The other less than 1% is comprised of various other gases. Hydrogen could be one of them, but the percentage is so minor that scientists tend not to calculate it.
