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 ...
Depiction of a hydrogen atom showing the diameter as about twice the Bohr model radius. (Image not to scale) A hydrogen atom is an atom of the chemical element hydrogen.The electrically neutral hydrogen atom contains a single positively charged proton in the nucleus, and a single negatively charged electron bound to the nucleus by the Coulomb force.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

Hydrogen is the chemical element with symbol H and atomic number 1. Hydrogen may also refer to: Dihydrogen, an allotrope of hydrogen; Hydrogen atom, about the physics of atomic hydrogen; Hydrogen ion; Hydron (chemistry), a.k.a. "proton" or "hydrogen" Isotopes of hydrogen. Hydrogen-2 (deuterium) Hydrogen-3 (tritium) Hydrogen-4; Hydrogen-5
The concentration of hydrogen ions and pH are inversely proportional; in an aqueous solution, an increased concentration of hydrogen ions yields a low pH, and subsequently, an acidic product. By definition, an acid is an ion or molecule that can donate a proton, and when introduced to a solution it will react with water molecules (H 2 O) to ...
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions , is a gas of diatomic molecules with the formula H 2 , sometimes called dihydrogen , [ 11 ] but more commonly called hydrogen gas , molecular hydrogen or simply hydrogen.
Symbol Name Atomic number Origin of symbol Ac: Actinium: 89: From Greek aktinos. Name restricted at one time to 227 Ac, an isotope of actinium. This named isotope later became the official name for element 89. AcA: Actinium A: 84: From actinium and A. Placeholder name given at one time to 215 Po, an isotope of polonium identified in the decay ...
