deuterium

deuterium (dōōtēr´ēəm), isotope of hydrogen with mass no. 2. The deuterium nucleus, called a deuteron, contains one proton and one neutron. Deuterium is also called heavy hydrogen, and water in which the hydrogen atoms are deuterium is called heavy water (deuterium oxide, D2O). Deuterons are sometimes used in particle accelerators, and heavy water is used in "swimming pool" nuclear reactors as a moderator.

deuterium

deuterium Isotope (D or H2) of hydrogen whose nuclei contain a neutron in addition to a proton. Deuterium occurs in water as D2O (heavy water), from which it is obtained by electrolysis. Heavy water is used in some nuclear reactors as a moderator that slows down free neutrons to increase nuclear fission. Properties: r.a.m. 2.0144.
