History

HistoryThe element Tantalum was discovered by G. Ekeberg in year 1802 in Sweden. Tantalum derived its name from King Tantalus, father of Niobe from Greek mythology.The element Rutherfordium was discovered by A. Ghiorso,M. Nurmia,J. Harris,K. Eskola and P. Eskola in year 1969 in Russia and United States. Rutherfordium derived its name from Ernest Rutherford, chemist and physicist.
