Deuterium (or hydrogen-2, symbol 2 H or deuterium, also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium, or hydrogen-1).The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus.Deuterium has a natural abundance in …

Deuterium (von altgriechisch δεύτερος deúteros, „der Zweite“) ist ein natürliches Isotop des Wasserstoffs.Sein Atomkern wird auch Deuteron genannt, er besteht aus einem Proton und einem Neutron.Deuterium (2 H) wird aufgrund seiner Masse auch als „schwerer Wasserstoff“ bezeichnet.Es wurde 1931 von den US-amerikanischen Chemikern Harold C. Urey und …

Deuterium of 2 H (occasioneel waterstof-2 genoemd) is een stabiele isotoop van waterstof met in de atoomkern een proton en een neutron.In plaats van de gebruikelijke notatie voor isotopen 2 H wordt meestal gebruikgemaakt van het symbool D. In tegenstelling tot tritium, een andere isotoop van waterstof, is deuterium stabiel.De abundantie op Aarde is laag: ongeveer 0,015% van alle ...

A deuterium lamp uses a tungsten filament and anode placed on opposite sides of a nickel box structure designed to produce the best output spectrum. Unlike an incandescent bulb, the filament is not the source of light in deuterium lamps. Instead an arc is created from the filament to the anode, a similar process to arc lamps.Because the filament must be very hot before it can …

Deuterium fusion, also called deuterium burning, is a nuclear fusion reaction that occurs in stars and some substellar objects, in which a deuterium nucleus and a proton combine to form a helium-3 nucleus. It occurs as the second stage of the proton–proton chain reaction, in which a deuterium nucleus formed from two protons fuses with another proton, but can also proceed …

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).The difference in mass between the reactants and products is manifested as either the release or absorption of energy.This difference in mass arises due to the difference in nuclear binding energy between …

Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions.In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2022, no design …

Deuterium–tritium fusion (sometimes abbreviated D+T) is a type of nuclear fusion in which one deuterium nucleus fuses with one tritium nucleus, giving one helium nucleus, one free neutron, and 17.6 MeV of energy. It is the most efficient type of fusion for fusion devices.. Tritium, one of the reactants required for this type of fusion, is radioactive.
