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 Fluorine was discovered by André-Marie Ampère in year 1886 in France. Fluorine derived its name derived its name from from the Latin fluere, meaning 'to flow'
