History

History
The element Yttrium was discovered by Johan Gadolin in year 1794 in Finland. Yttrium derived its name from from Ytterby, Sweden
The element Molybdenum was discovered by Carl Wilhelm Scheele in year 1781 in Sweden. Molybdenum derived its name derived its name from from the Greek word molybdos meaning 'lead'
