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 Krypton was discovered by William Ramsay in year 1898 in United Kingdom. Krypton derived its name derived its name from from the Greek kryptos, meaning 'hidden'
