  • What Is Deuterium? Facts and Uses - Science Notes and Projects
    Deuterium is the hydrogen isotope that has one proton and one neutron in its atomic nucleus In contrast, most hydrogen is the isotope called protium, which has one proton and no neutrons
  • Deuterium | Definition, Symbol, Production, Facts | Britannica
    Deuterium, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton) It is a stable atomic species found in natural hydrogen compounds to the extent of about 0 0156 percent
