==Explanation== Some or most of the hydrogen atoms in heavy water contain a neutron, making those heavy water hydrogen atoms about twice as heavy as normal hydrogen. However, the weight of the heavy water molecule as a whole is not substantially different from that of a normal water molecule because about 89% of the molecular weight of water comes...

A molecule of water contains two atoms of hydrogen and one of oxygen. Most water comprises of hydrogen/oxygen but a small percentage is composed of another hydrogen isotope, deuterium and oxygen. Deuterium differs from hydrogen by having one neutron in the nucleus of each atom. Deuterium water is given the formula D2O. There is approx. 1 part in 5000 D2O in normal water and it can be concentrated by electrolysis. D2O had a higher boiling point (101.4 °C) and melts at 3.6 °C

Water containing the isotope deuterium instead of hydrogen (relative molecular mass 20 as opposed to 18 for ordinary water). Its chemical properties are identical with those of ordinary water, but its physical properties differ slightly. It occurs in ordinary water in the ratio of about one part by mass of deuterium to 5,000 parts by mass of hydrog...
