deuterium

 (D) [doo-tēr´e-um]
the mass 2 isotope of hydrogen; it is available as a gas or heavy water and has been used as a tracer or indicator in metabolic studies.

deuterium (H)2

[dyo̅o̅tir′ē·əm]
Etymology: Gk, deuteros, second
a stable isotope of the hydrogen atom, used as a kinetic tracer. Also called heavy hydrogen. See also tritium.

(2H) (hī'drō-jen)
The isotope of hydrogen 2 of atomic weight 2; the less common stable isotope of hydrogen-2 making up 0.015% of the hydrogen-2 atoms occurring in nature.
Synonym(s): deuterium.

deuterium

(dootēr´ēəm), a stable isotope of the hydrogen atom, used as a tracer. Also called
heavy hydrogen. Deuterium oxide, or heavy water, is formed from an isotope of hydrogen, which has twice the weight of ordinary hydrogen (hence the name).
