History

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