⚛️
Add to dictionary

deuterium

 

[ djuːˈtɪərɪəm ]

Noun
Context #1 | Noun

chemistry, isotope

Deuterium is one of the two stable isotopes of hydrogen, represented by the symbol D or ²H. It contains one proton and one neutron in its nucleus, making it approximately twice as heavy as regular hydrogen. Deuterium is naturally present in all hydrogen sources, albeit in low concentrations (about 0.0156% of hydrogen in the oceans). It has various applications in nuclear fusion reactions and serves as a tracer in chemical research.

Synonyms

heavy hydrogen, ²H.

Examples of usage

  • Deuterium forms part of heavy water used in nuclear reactors.
  • The study of deuterium can provide insights into reaction mechanisms.
  • Scientists employ deuterium in spectroscopy to trace molecular pathways.

Etymology

The term 'deuterium' was coined in 1933 by Harold Urey, who was studying the isotopes of hydrogen at Columbia University. The name derives from the Greek word 'deuteros,' meaning 'second,' signifying its position as the second isotope of hydrogen. Urey's discovery was significant for its implications in both chemistry and physics, providing a clearer understanding of atomic structure. This led to the development of heavy water (D2O), which has applications in both nuclear technology and scientific research. Deuterium's unique properties have made it a critical element in various fields, including nuclear fusion, where its ability to participate in nuclear reactions plays a key role. Furthermore, its applications in tracing and labeling experiments have established it as an invaluable tool in both organic and inorganic chemistry.
