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 Potassium was discovered by Humphry Davy in year 1807 in United Kingdom. Potassium derived its name derived its name from from New Latin potassa, 'potash' (kalium in Latin)
