Heavy water (deuterium oxide, H 2O, D 2O) is a form of water that contains only deuterium ( H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope ( H or H, also called protium) that makes up most of the hydrogen in normal water. The presence of the heavier hydrogen isotope … See more Deuterium is a hydrogen isotope with a nucleus containing 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 … See more The physical properties of water and heavy water differ in several respects. Heavy water is less dissociated than light water at given temperature, and the true concentration of D … See more Different isotopes of chemical elements have slightly different chemical behaviors, but for most elements the differences are far too small to … See more Nuclear magnetic resonance Deuterium oxide is used in nuclear magnetic resonance spectroscopy when using water as … See more Semiheavy water Semiheavy water, HDO, exists whenever there is water with light hydrogen (protium, H) and deuterium … See more The US scientist and Nobel laureate Harold Urey discovered the isotope deuterium in 1931 and was later able to concentrate it in water.
