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 Radium was discovered by Pierre Curie in year 1898 in France. Radium derived its name derived its name from from the Latin radius, 'ray'
