n. Abbr. d
The nucleus of a deuterium isotope of hydrogen, composed of a proton and a neutron, regarded as a subatomic particle with unit positive charge.


(Chemistry) the nucleus of a deuterium atom, consisting of one proton and one neutron


(ˈdu təˌrɒn, ˈdyu-)

a positively charged particle consisting of a proton and a neutron, equivalent to the nucleus of an atom of deuterium. Compare triton.
