History

History
The element Manganese was discovered by Torbern Olof Bergman in year 1774 in Sweden. Manganese derived its name from corrupted from magnesia negra, see Magnesium
The element Astatine was discovered by Dale R. Corson in year 1940 in United States. Astatine derived its name derived its name from from the Greek astatos, 'unstable'
