Deuterium is a heavy hydrogen isotope. Heavy water contains deuterium atoms and is used in nuclear reactors. Semiheavy water (HDO) is more common than pure heavy water, while heavy-oxygen water is denser but lacks unique properties. Tritiated water is …

2020年1月28日 · Heavy water has the same chemical formula as any other water—H 2 O—with the exception that one or both of the hydrogen atoms are the deuterium isotope of hydrogen rather than the regular protium isotope (which is why heavy water is also known as deuterated water or D 2 O).

2025年3月21日 · heavy water (D2O), water composed of two atoms of deuterium, the hydrogen isotope with a mass double that of ordinary hydrogen, and one atom of oxygen. (Ordinary water has a composition represented by H 2 O.)

Deuterium Oxide is a stable, non-radioactive isotopic form of water, containing 2 atoms of deuterium (D) and one atom of oxygen (2D2O), with DNA-labeling activity. Upon ingestion of deuterium oxide, 2H is incorporated into the deoxyribose moiety of DNA of newly divided cells.

2023年7月3日 · Heavy water, scientifically called deuterium oxide, is a variant of water wherein the regular hydrogen atoms are replaced by heavy hydrogen, commonly known as deuterium. Alternatively, it can be expressed as 2H 2 O or D 2 O.

2018年10月15日 · 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.

2023年10月19日 · Heavy water or deuterium oxide (d2o) is a liquid with similar chemical properties to regular water but has different uses due to its greater mass and density.
