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 Bismuth was discovered by Claude François Geoffroy in year 1400 in unknown place. Bismuth derived its name derived its name from from German word, now obsolete
