Deuterium is an isotope of hydrogen with atomic mass of 2. It is represented by the symbols 2H or D. Deuterium is also known as heavy hydrogen. The nucleus of the deuterium atom, consisting of a proton and a neutron, is also known as a deuteron and is...

Deuterium is a non-radioactive isotope of hydrogen characterized by an extra proton. It is an odorless, flammable gas that exists in a diatomic state. The properties of deuterium and deuterium oxide are different from those of ordinary hydrogen and...

Isotope of hydrogen, chemical symbol 2H or D, atomic number 1 (but atomic weight approximately 2). Harold C. Urey won a Nobel Prize for its discovery and isolation. Its nucleus contains one proton and one neutron. A stable substance found in naturally...

A non-radioactive ISOTOPE of hydrogen, possessing one proton and one neutron in its nucleus. It comprises around 0.015 per cent of natural waters and is used in some nuclear reactors as a MODERATOR. Deuterium, like hydrogen, forms water on combination...

Deuterium, also called heavy hydrogen, is a stable isotope of hydrogen with a natural abundance in the oceans of Earth of approximately one atom in 6500 of hydrogen (~154 PPM). Deuterium thus accounts for approximately 0.015% (on a weight basis, 0.030%)...
