Deuterium

Definition

Deuterium, also known as heavy hydrogen, is a stable isotope of hydrogen with a nucleus containing one proton and one neutron, in contrast to the more common hydrogen isotope with only one proton. This unique structure of deuterium gives it distinct properties that are relevant in the context of transmutation and nuclear energy.

5 Must Know Facts For Your Next Test

1. Deuterium has a higher mass compared to the more common hydrogen isotope, which affects its behavior in various chemical and physical processes.
2. Deuterium is used as a tracer in biological and chemical studies due to its ability to be detected more easily than regular hydrogen.
3. Deuterium is an important component in the fusion reaction process, as it can be combined with tritium (another hydrogen isotope) to produce helium and release a large amount of energy.
4. Deuterium oxide, or heavy water, is used as a moderator in some nuclear reactors to slow down neutrons and enhance the fission reaction.
5. The enrichment of deuterium in water is a key step in the production of heavy water, which is used in certain types of nuclear reactors, such as CANDU reactors.
