The deuterium nucleus consists of a neutron and a proton; the nucleus of a protium (normal hydrogen) atom consists of just a proton. The additional neutron makes a deuterium atom roughly twice as heavy as a protium atom. A molecule of heavy water has two deuterium atoms in place of the two protium atoms of ordinary water.
Deuterium-depleted water has a lower concentration of deuterium (2 H) than occurs in nature at sea level. [1] Deuterium is a naturally-occurring, stable (non-radioactive) isotope of hydrogen with a nucleus consisting of one proton and one neutron. The nucleus of normal hydrogen (protium, 1 H) consists of one proton only, and no neutron.
There is thought to be little deuterium in the interior of the Sun and other stars, as at these temperatures the nuclear fusion reactions that consume deuterium happen much faster than the proton–proton reaction that creates deuterium. However, deuterium persists in the outer solar atmosphere at roughly the same concentration as in Jupiter ...

One gallon. 16 cups. It sounds like a lot, but considering that your body is made up of 60 percent water, it sort of makes sense that you'd need about that much to keep things running smoothly ...

Water portal; Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium atoms. In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water.
Semiheavy water is the result of replacing one of the protium in normal water with deuterium. [1] It exists whenever there is water with light hydrogen (protium, 1 H) and deuterium (D or 2 H) in the mix. This is because hydrogen atoms (1 H and 2 H) are rapidly exchanged between water molecules.
