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 Bromine was discovered by Antoine Jérôme Balard in year 1826 in France. Bromine derived its name derived its name from from the Greek bromos, meaning 'stench'
