| | #REDIRECT [[Physics:Quantum atoms/hydrogen#History]] |
| | |
| '''Timeline of hydrogen technologies''' is a support page for historical material linked from [[Physics:Quantum atoms/hydrogen]]. It summarizes selected milestones in the discovery, naming, production, storage, and use of hydrogen.
| |
| | |
| == Selected timeline ==
| |
| * '''1671''' - Robert Boyle describes the reaction of iron with acids, producing a flammable gas later understood as hydrogen.
| |
| * '''1766''' - [[Biography:Henry Cavendish|Henry Cavendish]] identifies hydrogen as a distinct gas and studies its properties.
| |
| * '''1783''' - Antoine Lavoisier gives hydrogen its modern name, from Greek roots meaning water-former.
| |
| * '''1800''' - Water electrolysis demonstrates a controlled way to produce hydrogen and oxygen from water.
| |
| * '''1839''' - William Grove demonstrates an early fuel cell using hydrogen and oxygen.
| |
| * '''Late nineteenth century''' - Hydrogen spectroscopy becomes important in atomic physics, especially through the Balmer and Rydberg formulas.
| |
| * '''1913''' - [[Biography:Niels Bohr|Niels Bohr]] uses hydrogen as the central example in the Bohr model of atomic structure.
| |
| * '''Twentieth century''' - Hydrogen becomes important in ammonia synthesis, petroleum refining, cryogenics, rockets, and nuclear fusion research.
| |
| * '''Twenty-first century''' - Hydrogen technologies are studied for energy storage, fuel cells, industrial decarbonization, and synthetic fuels.
| |
| | |
| == Quantum relevance ==
| |
| Hydrogen is technologically important, but it is also central to quantum physics because it is the simplest atom with a bound electron. Its spectrum, isotope structure, and precision measurements connect directly to [[Physics:Quantum atoms/hydrogen]], [[Physics:Quantum atoms/energy level]], and [[Physics:Quantum Spectral lines and series]].
