A water molecule is made of one oxygen atom bound to two hydrogen atoms, hence its chemical formula: H 2 O. But that’s not the hydrogen they’re talking about. Hydrogen can also be a gas ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

The chemical formula for water is H 2 O (two hydrogen atoms and one oxygen atom), and hydrogen water is simply water with more hydrogen (H) added to it. The concept seems to have started decades ...
