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 Chromium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Chromium derived its name derived its name from from the Greek word chroma, meaning 'color'
