History

History
The element Gallium was discovered by Lecoq de Boisbaudran in year 1875 in France. Gallium derived its name from from Gallia, the Latin name for France
The element Osmium was discovered by Smithson Tennant in year 1803 in United Kingdom. Osmium derived its name derived its name from from the Greek osmè, meaning 'smell'
