History

HistoryThe 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'.The element Scandium was discovered by F. Nilson in year 1879 in Sweden. Scandium derived its name from Scandia, the Latin name for Scandinavia.
