History	The element Helium was discovered by P. Janssen and N. Lockyer in year 1868 in Sweden and United Kingdom. Helium derived its name from the Greek word helios, meaning 'sun'.	The element Bismuth was discovered by C.F. Geoffroy in year 1753 in one. Bismuth derived its name from German word, now obsolete.
