Hydrogen - Wikipedia
WebHydrogen 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, but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.
Hydrogen - Simple English Wikipedia, the free encyclopedia
WebHydrogen is a chemical element at the start of the periodic table. It has the symbol H and atomic number 1. It also has a standard atomic weight of 1.008, which makes it the lightest element in the periodic table. Hydrogen is the most common chemical element in the Universe, making up 75% of all normal matter (by mass).
Hydrogen atom - Wikipedia
WebA hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.
Hydrogen production - Wikipedia
WebHydrogen gas is produced by several industrial methods. Nearly all of the world's current supply of hydrogen is created from fossil fuels.: 1 Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas.

Natural hydrogen - Wikipedia
WebNatural hydrogen (known as white hydrogen, geologic hydrogen or gold hydrogen), is hydrogen that is formed by natural processes (as opposed to hydrogen produced in a laboratory or in industry). By contrast green hydrogen is produced from renewable energy sources, while grey, brown, blue or black hydrogen are obtained from fossil fuels . [4]
Isotopes of hydrogen - Wikipedia
WebHydrogen is the only element whose isotopes have different names that remain in common use today: the 2 H (or hydrogen-2) isotope is deuterium and the 3 H (or hydrogen-3) isotope is tritium. The symbols D and T are sometimes used for deuterium and tritium. The IUPAC accepts the D and T symbols, but recommends using standard isotopic symbols (2 ...
Hydrogen compounds - Wikipedia
WebHydrogen compounds are compounds containg the element hydrogen. In these compounds, hydrogen can form in the +1 and -1 oxidation states. Hydrogen can form compounds both ionically and in covalent substances. It is a part of many organic compounds such as hydrocarbons as well as water and other organic substances.
Hydrogen atom - Simple English Wikipedia, the free encyclopedia
WebA hydrogen atom is an atom of the chemical element hydrogen. Its parts are a single negatively-charged electron that circles a single positively-charged nucleus of the hydrogen atom. The nucleus of hydrogen consists of only a single proton (in the case of hydrogen-1 or protium ), or it may also include one or more neutrons (giving deuterium ...
