History

History
The element Arsenic was discovered by Bronze Age in year 1250 in unknown place. Arsenic derived its name from English word (Latin arsenicum)
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'
