Deuterium is a heavier stable isotope of ordinary hydrogen. It is a colorless, odorless, non-toxic flammable gas. Its boiling point is -249.5℃. Like molecular hydrogen, diatomic deuterium molecules also have positive and secondary isomerism. At room temperature, the equilibrium composition of a mixture of positive and secondary isomers of deuterium is 2:1, and this deuterium is called normal deuterium. Lowering the temperature facilitates the conversion to n-deuterium. At 20.4K, the equilibrium mixture contains 97.8% positive deuterium, which is called equilibrium deuterium.
