Triatomic hydrogen or H 3 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.
The three hydrogen atoms in the molecule form an equilateral triangle, with a bond length of 0.90 Å on each side. The bonding among the atoms is a three-center two-electron bond , a delocalized resonance hybrid type of structure.
Linear triatomic molecules owe their geometry to their sp or sp 3 d hybridised central atoms. Well-known linear triatomic molecules include carbon dioxide (CO 2) and hydrogen cyanide (HCN). Xenon difluoride (XeF 2) is one of the rare examples of a linear triatomic molecule possessing non-bonded pairs of electrons on the central atom.

Triatomic (composed of three atoms). Examples include O 3 . Tetratomic (composed of 4 atoms), Pentatomic (composed of 5 atoms), Hexatomic (composed of 6 atoms), Heptatomic (composed of 7 atoms), Octatomic (composed of 8 atoms) Atomicity may vary in different allotropes of the same element.
Tritium (from Ancient Greek τρίτος (trítos) ' third ') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive ...
