Because of its simple atomic structure, consisting only of a proton and an electron, the hydrogen atom, together with the spectrum of light produced from it or absorbed by it, has been central to the development of the theory of atomic structure. This reaction closely resembles the Schikorr reaction observed in anaerobic oxidation of ferrous hydroxide in contact with water. However, this electrolysis process is currently more expensive than creating hydrogen from methane and the efficiency of energy conversion is inherently low. Hydrogen is often produced by reacting water with methane and carbon monoxide, which causes the removal of hydrogen from hydrocarbons at very high temperatures, with 48% of hydrogen production coming from steam reforming. Other, highly unstable nuclei (4H to 7H) have been synthesized in the laboratory but not observed in nature. Original supporting documentation for dependents must be included in the application. [9][note 1] Stars such as the Sun are mainly composed of hydrogen in the plasma state. The term "hydride" suggests that the H atom has acquired a negative or anionic character, denoted H, and is used when hydrogen forms a compound with a more electropositive element. Key consumers of H2 include hydrodealkylation, hydrodesulfurization, and hydrocracking. In 17661781, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance,[12] and that it produces water when burned, the property for which it was later named: in Greek, hydrogen means "water-former".

Commercial bulk hydrogen is usually produced by the steam reforming of natural gas[116] with release of atmospheric greenhouse gas or with capture using CCS and climate change mitigation. Both of these forms result from writing the letter without taking the pen from the paper, the right-hand vertical bar being thus foreshortened and the horizontal stroke rounded.
