History

History
The element Chromium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Chromium derived its name from from the Greek word chroma, meaning 'color'
The element Gallium was discovered by Lecoq de Boisbaudran in year 1875 in France. Gallium derived its name derived its name from from Gallia, the Latin name for France
