History
History |
The element Thallium was discovered by William Crookes in year 1861 in United Kingdom. Thallium derived its name from from the Greek thallos, 'green twig' |
The element Bismuth was discovered by Claude François Geoffroy in year 1400 in unknown place. Bismuth derived its name derived its name from from German word, now obsolete |
