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 Thallium was discovered by William Crookes in year 1861 in United Kingdom. Thallium derived its name derived its name from from the Greek thallos, 'green twig'
