deu·te·ri·um

 (do͞o-tîr′ē-əm, dyo͞o-)
n.
A naturally occurring isotope of hydrogen, H-2, having one proton and one neutron in the nucleus.

deuterium

(djuːˈtɪərɪəm)
n
(Elements & Compounds) a stable isotope of hydrogen, occurring in natural hydrogen (156 parts per million) and in heavy water: used as a tracer in chemistry and biology. Symbol: D or 2H; atomic no: 1; atomic wt: 2.014; boiling pt: –249.7°C
[C20: New Latin; see deutero-, -ium; from the fact that it is the second heaviest hydrogen isotope]

deu•te•ri•um

deu·te·ri·um

(do͞o-tîr′ē-əm)
An isotope of hydrogen whose nucleus has one proton and one neutron and whose atomic mass is 2. Deuterium is used widely as a tracer for analyzing chemical reactions, and it combines with oxygen to form heavy water. Also called heavy hydrogen. See more at hydrogen. See Note at heavy water.

deuterium

An isotope of hydrogen. Its nucleus contains one proton and one neutron and has a relative atomic mass of two.
