Deuterium Gas
Designations:
Chemical Name: Deuterium
Chemical Formula: D and 2H
Description:
Deuterium is a stable, naturally-occurring isotope of hydrogen with an atomic mass of two (one proton and one neutron). There is approximately 1 part of deuterium to 5000 parts of normal hydrogen found in nature. Deuterium is sometimes called heavy hydrogen. When combined with oxygen, the oxide form is referred to as heavy water and is used to moderate fission reactions in certain nuclear reactors.
Deuterium, stable, non-radioactive isotope of hydrogen with
atomic weight 2.01363 and symbol D, or 2H. It is commonly called heavy hydrogen because its atomic weight is approximately double that of ordinary hydrogen, but it has identical chemical properties. Deuterium has about twice the atomic weight of normal hydrogen because its nucleus contains a proton and a neutron, instead of just a proton. Hydrogen as it occurs in nature contains approximately 0.02 percent of deuterium. The boiling point of deuterium is -249.49° C (-417.08°F), or 3.28° C (5.90° F) higher than that of ordinary hydrogen. Heavy water (deuterium oxide, D2O) boils at 101.42° C (214.56°F) as compared to 100° C (212° F), the boiling point of ordinary water. It freezes at 3.81° C (38.86° F) as compared to 0° C (32°F) for ordinary water. Its density at room temperature is 10.79 percent greater than that of ordinary water.
