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 Gadolinium was discovered by Jean Charles Galissard de Marignac in year 1880 in Switzerland. Gadolinium derived its name derived its name from from Johan Gadolin, chemist, physicist and mineralogist
