			'''Timeline of hydrogen technologies''' is a historical overview of selected discoveries, instruments, and technologies connected with hydrogen. It supports the history section of [[Physics:Quantum atoms/hydrogen]].

			== Timeline ==
			* '''1671''' - Robert Boyle describes the reaction of iron filings with dilute 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 split water into hydrogen and oxygen.
			* '''1839''' - William Grove demonstrates an early hydrogen-oxygen fuel cell.
			* '''1885''' - [[Biography:Johann Balmer\|Johann Balmer]] describes regularities in hydrogen spectral lines.
			* '''1888''' - [[Biography:Johannes Rydberg\|Johannes Rydberg]] generalizes spectral formulas used for hydrogen and other atoms.
			* '''1913''' - [[Biography:Niels Bohr\|Niels Bohr]] uses hydrogen as the central example in his quantum model of the atom.
			* '''1931''' - Deuterium is identified as a stable isotope of hydrogen.
			* '''Mid twentieth century''' - Hydrogen becomes important in cryogenics, rocketry, ammonia synthesis, and nuclear fusion research.
			* '''Late twentieth century''' - Fuel-cell systems and hydrogen storage materials become active engineering fields.
			* '''Twenty-first century''' - Hydrogen technologies are studied for energy storage, fuel cells, industrial decarbonization, synthetic fuels, and low-carbon chemical production.

			== 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, isotopes, and precision measurements connect hydrogen technology history with atomic spectroscopy and quantum theory.

	'''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]].~~
