History

ParameterChlorineFluorine
HistoryThe element Chlorine was discovered by W. Scheele in year 1774 in Sweden. Chlorine derived its name from the Greek word chloros, meaning 'greenish yellow'.The element Fluorine was discovered by A.-M. Ampère in year 1810 in France. Fluorine derived its name from the Latin fluere, meaning 'to flow'.
