deuterium
Also known as H-2, hydrogen-2, 2H, Heavy hydrogen, D, 重水素, ²H
Deuterium (hydrogen-2, symbol H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, H. The deuterium nucleus (deuteron) contains one proton and one neutron, whereas the far more common H has no neutrons.
AI overview
Deuterium is a heavier form of hydrogen that contains an extra neutron in its nucleus, making it roughly twice as heavy as ordinary hydrogen. Although deuterium is much rarer than regular hydrogen, it occurs naturally and is one of only two stable forms of hydrogen found in nature.

Deuterium (hydrogen-2, symbol H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, H. The deuterium nucleus (deuteron) contains one proton and one neutron, whereas the far more common H has no neutrons.
The name deuterium comes from Greek deuteros, meaning "second". American chemist Harold Urey discovered deuterium in 1931. Urey and others produced samples of heavy water in which the H had been highly concentrated. The discovery of deuterium won Urey a Nobel Prize in 1934.
