Deuterium (or hydrogen-2, symbol H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1). The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons … See more Chemical symbol Deuterium is frequently represented by the chemical symbol D. Since it is an isotope of hydrogen with mass number 2, it is also represented by H . IUPAC allows both D and H , although H … See more Data for molecular deuterium Formula: D2 or 1H 2 • Density: 0.180 kg/m at STP (0 °C, 101325 Pa). • Atomic weight: 2.0141017926 Da.
