deuterium

deuterium (dOOtēr'ēum) [key], isotope of hydrogen with mass no. 2. The deuterium nucleus, called a deuteron, contains one proton and one neutron. Deuterium is also called heavy hydrogen, and water in which the hydrogen atoms are deuterium is called heavy water (deuterium oxide, D₂O). Deuterons are sometimes used in particle accelerators, and heavy water is used in “swimming pool” nuclear reactors as a moderator.
