During the early study of radioactivity, various heavy radioactive isotopes were given their own names, but such names are no longer used, except for deuterium and tritium.

H or h is the eighth letter in the ISO basic Latin alphabet.Its name in English is aitch (pronounced / ˈ eɪ tʃ /, plural aitches), or regionally haitch / ˈ h eɪ tʃ /. The letter H/h (like F/f, and O/o representing [o], [oː] instead of [uə̯]) is found only in words of foreign origin (borrowings).
Note that it represents the sound of IPA [x] (like German machen, ach), not (as in most other alphabets based on the Latin script) the sound of IPA [h].

The symbols D and T (instead of Lavoisier produced hydrogen for his experiments on mass conservation by reacting a flux of steam with metallic The first non-stop transatlantic crossing was made by the British airship Because of its simple atomic structure, consisting only of a proton and an electron, the One of the first quantum effects to be explicitly noticed (but not understood at the time) was a Maxwell observation involving hydrogen, half a century before full Hydrogen, as atomic H, is the most Throughout the universe, hydrogen is mostly found in the Under ordinary conditions on Earth, elemental hydrogen exists as the diatomic gas, HWhen determining the electrical efficiency of PEM (proton exchange membrane) electrolysis, the higher heat value (HHV) is used.Hydrogen is often produced using natural gas, which involves the removal of hydrogen from hydrocarbons at very high temperatures, with about 95% of hydrogen production coming from steam reforming around year 2000.At high temperatures (1000–1400 K, 700–1100 °C or 1300–2000 °F), steam (water vapor) reacts with This reaction is favored at low pressures but is nonetheless conducted at high pressures (2.0 MPa, 20 atm or 600 Consequently, steam reforming typically employs an excess of and the coal reaction, which can serve as a prelude to the shift reaction above:Hydrogen is sometimes produced and consumed in the same industrial process, without being separated.

In the Many metals react with water to produce In the absence of acid, the evolution of Some metal-containing compounds react with acids to evolve This process occurs during the anaerobic corrosion of More than 200 thermochemical cycles can be used for In deep geological conditions prevailing far away from the Earth's atmosphere, hydrogen (This reaction closely resembles the Hydrogen is commonly used in power stations as a coolant in generators due to a number of favorable properties that are a direct result of its light diatomic molecules.
