Triatomic hydrogen - Wikipedia
Triatomic hydrogen or H3 is an unstable triatomic molecule containing only hydrogen. Since this molecule contains only three atoms of hydrogen it is the simplest triatomic molecule [1] and it is relatively simple to numerically solve the quantum mechanics description of the particles.
Tritium - Wikipedia
Tritium is the heaviest particle-bound isotope of hydrogen. It is one of the few nuclides with a distinct name. The use of the name hydrogen-3, though more systematic, is much less common. Naturally occurring tritium is extremely rare on Earth.
Helium-3 - Wikipedia
Helium-3 (3He[1][2] see also helion) is a light, stable isotope of helium with two protons and one neutron. (In contrast, the most common isotope, helium-4, has two protons and two neutrons.) Helium-3 and protium (ordinary hydrogen) are the only stable nuclides with more protons than neutrons. It was discovered in 1939.

Tritium Facts (Hydrogen Isotope) - Science Notes and Projects
Jun 18, 2024 · Tritium is the radioactive isotope of the element hydrogen. It is also known as hydrogen-3 or using the shorthand notation T or 3 H in chemical formulas and reactions. The nucleus of the tritium atom, called a triton, contains one proton and two neutrons.
10 Interesting Facts About Radioactive Tritium - ThoughtCo
Jan 9, 2020 · Tritium is also known as hydrogen-3 and has an element symbol T or 3 H. The nucleus of a tritium atom is called a triton and consists of three particles: one proton and two neutrons. The word tritium comes from Greek the word "tritos", which means "third". The other two isotopes of hydrogen are protium (most common form) and deuterium.
Hydrogen-3 - isotopic data and properties - ChemLin
Hydrogen-3 - also known as tritium - is a radioactive isotope of hydrogen that occurs naturally in very small amounts in the atmosphere. It has a half-life of about 12.3 years and beta decays into helium-3. Tritium is used in the nuclear industry as a fuel in nuclear reactors and in the manufacture of nuclear weapons.
Hydrogen | H (Element) - PubChem
Hydrogen was first recognized as a distinct element by Henry Cavendish in 1766. Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen.
To be or not to be: the early history of H3 and H3+ | Philosophical ...
Nov 13, 2012 · More than 15 years earlier, one can find in the chemical literature references to the possible existence of H 3, which a few scientists thought might represent the newly discovered helium gas. Originally hypothesized to be a solar element, in 1895, He was unexpectedly found in terrestrial minerals [2].
