History

History
The element Helium was discovered by Pierre Janssen in year 1895 in Sweden and United Kingdom. Helium derived its name from from the Greek word helios, meaning 'sun'
The element Manganese was discovered by Torbern Olof Bergman in year 1774 in Sweden. Manganese derived its name derived its name from corrupted from magnesia negra, see Magnesium
