Definition of tritium in English:

tritium

noun ˈtrɪtɪəmˈtrɪdiəm

mass nounChemistry

A radioactive isotope of hydrogen with a mass approximately three times that of the usual isotope.
Example sentencesExamples
- Although tritium can be a gas, its most common form is in water, because, like non-radioactive hydrogen, radioactive tritium reacts with oxygen to form water.
- The isotopes tritium and helium - 3 were used to identify and date ground water recharged in the past 50 years.
- This particular arrangement of nucleons is unstable and so tritium readily undergoes radioactive decay to yield a helium atom.
- Although many nuclei can be fused, this subject normally refers to fusion of hydrogen isotopes deuterium or tritium to form helium.
- These products contain tiny glass vials filled with a radioactive gas such as tritium.

Discovered in 1934, tritium has two neutrons as well as a proton in the nucleus. It occurs in minute traces in nature and can be made artificially from lithium or deuterium in nuclear reactors; it is used as a fuel in thermonuclear bombs

Origin

1930s: from modern Latin, from Greek tritos 'third'.
