History

History
The element Fluorine was discovered by André-Marie Ampère in year 1886 in France. Fluorine derived its name from from the Latin fluere, meaning 'to flow'
The element Lanthanum was discovered by Carl Gustaf Mosander in year 1839 in Sweden. Lanthanum derived its name derived its name from from the Greek lanthanein, meaning 'to lie hidden'
