The trihydrogen cation or protonated molecular hydrogen (IUPAC name: hydrogenonium ion) is a cation (positive ion) with formula H + 3, consisting of three hydrogen nuclei sharing two electrons. The trihydrogen cation is one of the most abundant ions in the universe.
3 ions can be made in a duoplasmatron where an electric discharge passed through low pressure molecular hydrogen. This causes some H 2 to become H + 2. Then H 2 + H + 2 → H + 3 + H. The reaction is exothermic with an energy of 1.7 eV, so the ions produced are hot with much vibrational energy.
Ozone, O 3 Trihydrogen cation, H 3 + Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element. Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously.
In chemistry, the valence (US spelling) or valency (British spelling) of an atom is a measure of its combining capacity with other atoms when it forms chemical compounds or molecules. Valence is generally understood to be the number of chemical bonds that each atom of a given chemical element typically forms.
Instead, each oxygen atom is linked by a strong (covalent) bond to only two hydrogen atoms, as a water molecule, and there are molecules of dihydrogen inserted in the voids of the water molecules network. [6] Structurally, it is thus a 2(H 2 O)·H 2 stoichiometric combination. At 600 GPa and 7000 K, the compound density is calculated to be 4.3 ...
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 hydrogen ...
In chemistry, the hydron, informally called proton, [2] is the cationic form of atomic hydrogen, represented with the symbol H +The general term "hydron", endorsed by IUPAC, encompasses cations of hydrogen regardless of isotope: thus it refers collectively to protons (1 H +) for the protium isotope, deuterons (2 H + or D +) for the deuterium isotope, and tritons (3 H + or T +) for the tritium ...
The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
