History

History
The element Hydrogen was discovered by Henry Cavendish in year 1766 in United Kingdom. Hydrogen derived its name from from the Greek elements hydro- and -gen meaning 'water-forming'
The element Iron was discovered by unknown in year 2000 BC in unknown place. Iron derived its name derived its name from from English word (ferrum in Latin)
