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 Scandium was discovered by Lars Fredrik Nilson in year 1879 in Sweden. Scandium derived its name derived its name from from Scandia, the Latin name for Scandinavia
