A deuterium nucleus; namely, a proton and a neutron. It is used in nuclear applications, such as the bombardment of molybdenum plates to create technetium plates. With an electron, it forms the stable hydrogen isotope of deuterium or "heavy hydrogen", symbol D, atomic wt. 2. Water with both hydrogens replaced by deuterium is called "heavy water" (D2O), and is used as a moderator in the harnessing of nuclear fuels.
I swear that deuterons have somethingy to do with the book of Deuteronomy, 5th book of the Old Testament.
