History

History
The element Cerium was discovered by Martin Heinrich Klaproth in year 1803 in Germany and Sweden. Cerium derived its name from from the then recently discovered asteroid Ceres, considered a planet at the time
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'
