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 is preferred. A distinct chemical symbol is used for convenience because of the isotope's common use … Meer weergeven 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).
