History

ParameterCobaltHydrogen
HistoryThe element Cobalt was discovered by G. Brandt in year 1735 in Sweden. Cobalt derived its name from the German word Kobold, meaning 'goblin'.The element Hydrogen was discovered by H. Cavendish in year 1766 in United Kingdom. Hydrogen derived its name from the Greek elements hydro- and -gen meaning 'water-forming'.
