Deuterium, also known as heavy hydrogen, is a stable isotope of hydrogen. Its nucleus consists of one proton and one neutron, differentiating it from ordinary hydrogen, which has only a proton. Deuterium is found naturally in water, where it replaces ordinary hydrogen atoms to form heavy water (D2O). The abundance of deuterium in terrestrial water is approximately 156 deuterium atoms per million hydrogen atoms. This isotope was discovered in 1932 by Harold Urey, who was awarded the Nobel Prize in Chemistry for his work.

Deuterium has several significant applications. In nuclear reactors, heavy water serves as a neutron moderator, slowing down fast neutrons to increase the probability of nuclear fission. This is crucial for sustaining controlled nuclear chain reactions. Deuterium is also used in scientific research, particularly in nuclear magnetic resonance (NMR) spectroscopy, where its distinct spectral properties allow for the study of molecular structures. Furthermore, deuterium labeling is employed in metabolic studies and in the synthesis of specialized chemical compounds, as the change in mass can alter reaction rates and thermodynamic properties.

The properties of deuterium differ from those of ordinary hydrogen primarily due to its increased mass. This mass difference influences its chemical reaction rates, boiling point, and melting point. While chemically similar to hydrogen, these subtle variations are exploited in various scientific and industrial applications. The deuterium-related field encompasses the study, production, and utilization of this important hydrogen isotope.
