History

History
The element Chlorine was discovered by Carl Wilhelm Scheele in year 1774 in Sweden. Chlorine derived its name from from the Greek word chloros, meaning 'greenish yellow'
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'
