Deuterium - Wikipedia
网页Deuterium (hydrogen-2, symbol 2H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, 1 H. The deuterium nucleus, called a deuteron, contains one proton and one neutron, whereas the far more common 1 H has no neutrons.

网页Deuterium is a stable atomic species that is found in natural hydrogen compounds to an extent of about 0.0156%. Hence, it is not radioactive. Approximately 156.25 ppm of deuterium is present in the oceans which are equal to one atom in 6,400 of hydrogen. Deuterium got its name from the Greek word deuterons, meaning “second”.
