History

ParameterManganeseTechnetium
HistoryThe element Manganese was discovered by W. Scheele in year 1774 in Sweden. Manganese derived its name from magnesia negra.The element Technetium was discovered by C. Perrier and E. Segrè in year 1937 in Italy. Technetium derived its name from the Greek tekhnètos meaning 'artificial'.
