History

ParameterHydrogenCobalt
HistoryThe 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'.The element Cobalt was discovered by G. Brandt in year 1735 in Sweden. Cobalt derived its name from the German word Kobold, meaning 'goblin'.
