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 Mendelevium was discovered by Lawrence Berkeley National Laboratory in year 1955 in United States. Mendelevium derived its name derived its name from from Dmitri Mendeleev, chemist and inventor
