History

ParameterArsenicKrypton
HistoryThe element Arsenic was discovered by Arabic alchemist in year ca. 800 AD. Arsenic derived its name English word (Latin arsenicum).The element Krypton was discovered by W. Ramsay and W. Travers in year 1898 in United Kingdom. Krypton derived its name from the Greek kryptos, meaning 'hidden'.
