deuterium
/dju:'tiəriəm/
Definition
- Noun:
- A stable isotope of hydrogen: Deuterium is a form of hydrogen whose atomic nucleus contains one proton and one neutron, unlike the most common form of hydrogen which has only a proton. It is also known as "heavy hydrogen."
Usage
- Deuterium is a non-radioactive isotope.
- It is used in scientific research, nuclear reactors, and as a tracer in chemical and biological studies.
- The chemical symbol for deuterium is D or ²H.
Examples
- Noun:
- Deuterium is twice as heavy as ordinary hydrogen.
- The fusion of deuterium and tritium releases a tremendous amount of energy.
- Scientists used deuterium to label the molecules in the experiment.
Advanced Usage
- "Deuterium oxide" (D₂O): Commonly known as "heavy water," this is water in which the hydrogen atoms are replaced by deuterium atoms. It is used as a moderator in certain types of nuclear reactors.
- The nuclear reactor uses deuterium oxide as a neutron moderator.
Variants and Related Words
- Deuteron (n): The nucleus of a deuterium atom, consisting of one proton and one neutron.
- The deuteron is a stable particle.
Synonyms
- Heavy hydrogen: A common synonym for deuterium.
Related Phrases and Compounds
- Deuterium-tritium fusion: A nuclear fusion reaction between deuterium and tritium nuclei, which is a primary candidate for energy production in fusion power research.
- Deuterium-tritium fusion is the goal of many experimental reactors.
- Deuterium labeling: A technique in chemistry and biochemistry where deuterium atoms are used to replace hydrogen atoms in a molecule to trace its path in a reaction or metabolic process.
- Deuterium labeling helped track the drug's metabolism in the body.
Noun
-
an isotope of hydrogen which has one neutron (as opposed to zero neutrons in hydrogen)
