Now I really feel dumb! Errr, make that 2 H and 1 O.
Heavy water is chemically the same as regular (light) water, but with the two hydrogen atoms (as in H2O) replaced with
deuterium atoms (hence the symbol D2O). Deuterium is an isotope of hydrogen; it has one extra neutron. Thus the deutrium
atom consists of one proton and one neutron in the atomic nucleus and one orbiting electron. It is the extra neutron that makes
heavy water "heavy", about 10% heavier in fact.
But what does this have to do with more Oxygen?
