Deuterium oxide is used in nuclear reactor as
WebOct 15, 2024 · Deuterium oxide (D 2 O), aka “heavy water”, is the form of water that contains two atoms of the 2 H, or D, isotope. The term heavy water is also used for water in which 2 H atoms replace only some of the 1 H atoms. In this case, rapid exchange between the two isotopes forms twice as many “semiheavy” HDO molecules as D 2 O..

Heavy water (deuterium oxide, H 2O, D 2O) is a form of water that contains only deuterium ( H or D, also known as heavy hydrogen) rather than the common hydrogen-1 isotope ( H or H, also called protium) that makes up most of the hydrogen in normal water. The presence of the heavier hydrogen … See more Deuterium is a hydrogen isotope with a nucleus containing a neutron and a proton; the nucleus of a protium (normal hydrogen) atom consists of just a proton. The additional neutron makes a deuterium atom roughly twice … See more The physical properties of water and heavy water differ in several respects. Heavy water is less dissociated than light water at given temperature, and the true concentration of D ions is less than H ions would be for a light water sample at the same temperature. … See more Different isotopes of chemical elements have slightly different chemical behaviors, but for most elements the differences are far too small to have a biological effect.
