Deuterium vs. Hydrogen: What's the Difference?
Deuterium is a stable isotope of hydrogen with one proton and one neutron, while hydrogen typically has only one proton and no neutrons.
Hydrogen is the simplest and most abundant element in the universe, consisting of one proton and one electron. Deuterium, on the other hand, is a heavier isotope of hydrogen, containing one proton, one neutron, and one electron. This additional neutron in deuterium contributes to its greater mass compared to ordinary hydrogen, which lacks a neutron.
In chemical reactions, hydrogen exhibits properties typical of a light gas, reacting quickly and often explosively with many elements. Deuterium, while chemically similar to hydrogen, reacts more slowly due to its higher mass, affecting reaction rates and mechanisms. This difference is crucial in studies of reaction kinetics and isotope effects in chemistry.
Hydrogen is key in various industrial processes, such as the production of ammonia for fertilizers and refining petroleum. Deuterium, with its unique nuclear properties, is used in nuclear fusion experiments and as a tracer in scientific research. Its presence in water, known as heavy water, is utilized in certain types of nuclear reactors.
The abundance of hydrogen in nature, particularly in water and organic compounds, is vastly higher than that of deuterium. Deuterium, though naturally occurring, is present only in trace amounts in Earth's water. Its detection and separation from hydrogen require specialized techniques due to their physical similarities.

A molecule of this molecular species
A sample of the element/molecule.
A gaseous element, colorless, tasteless, and odorless, the lightest known substance, being fourteen and a half times lighter than air (hence its use in filling balloons), and over eleven thousand times lighter than water. It is very abundant, being an ingredient of water and of many other substances, especially those of animal or vegetable origin. It may by produced in many ways, but is chiefly obtained by the action of acids (as sulphuric) on metals, as zinc, iron, etc. It is very inflammable, and is an ingredient of coal gas and water gas. It is standard of chemical equivalents or combining weights, and also of valence, being the typical monad. Symbol H. Atomic weight 1.
