History

History
The element Molybdenum was discovered by Carl Wilhelm Scheele in year 1781 in Sweden. Molybdenum derived its name from from the Greek word molybdos meaning 'lead'
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
