Deuterium (hydrogen-2, symbol 2 H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, 1 H. The deuterium nucleus (deuteron) contains one proton and one neutron, whereas the far more common 1 H has no neutrons. The name deuterium comes from Greek deuteros, meaning "second".

Feb 9, 2021 · Deuterium is a stable isotopic tracer that is detectable using infrared spectrometry or mass spectrometry. Deuterated drugs act differently from drugs made using normal hydrogen, offering a host of medical possibilities.

Jan 13, 2023 · Deuterium isotopes are distributed in molecules that contain hydrogen, including, importantly, in all forms of water – also water in our bodies. There’s 33 grams of deuterium in every cubic metre of seawater, so that the ocean contains tons of the isotope.

Jan 9, 2025 · Deuterium, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). It is a stable atomic species found in natural hydrogen compounds to the extent of about 0.0156 percent.

Deuterium | H2 | CID 24523 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

Apr 2, 2019 · Deuterium is one of only five stable nuclides that has an odd number of both protons and neutrons. In most atoms, odd numbers of protons and neutrons are unstable with respect to beta decay. The presence of deuterium has been confirmed on other planets in the solar system and in the spectra of stars.

Sep 13, 2007 · Deuterium is an isotope of the chemical element hydrogen. Unlike normal hydrogen, which has one proton, deuterium has one proton and one neutron. This isotope is non-radioactive, and is found in small quantities wherever hydrogen is present. It is primarily used in nuclear fusion, as a moderator for fission reactors, and in nuclear magnetic ...
