Deuterium ... Deuterium (hydrogen-2, symbol 2H or D, also known as heavy hydrogen) is one of two stable isotopes of hydrogen; the other is protium, or hydrogen-1, 1 H. The deuterium nucleus …

Feb 9, 2021 · Deuterium is the hydrogen isotope that has one proton and one neutron in its atomic nucleus. In contrast, most hydrogen is the isotope called protium, which has one proton and no …

Dec 26, 2025 · Deuterium, isotope of hydrogen with a nucleus consisting of one proton and one neutron, which is double the mass of the nucleus of ordinary hydrogen (one proton). It is a stable atomic …

Jan 13, 2023 · Deuterium is a stable isotope of hydrogen, which, unlike “normal” hydrogen atoms, or protium, also contains a neutron.

Mar 3, 2025 · Discover 36 fascinating facts about deuterium, the heavy hydrogen isotope, and its crucial role in science, energy, and the universe.

5 days ago · Discover the immense, quantified inventory of deuterium on Earth, where this heavy hydrogen is stored, and its critical value as fuel for fusion power.

Deuterium is subsequently produced by the slow stellar proton–proton chain, but rapidly destroyed by exothermic fusion reactions. The deuterium–deuterium reaction has the second-lowest energy …

Apr 2, 2019 · What is deuterium? Here's a look at what deuterium is, where you might find it, and some of its uses.

Deuterium is an isotope of hydrogen but it is chemically identical. It is a colorless, odorless gas. It is easily ignited. Once ignited it burns with a pale blue, almost invisible flame. The vapors are lighter …
