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 Ruthenium was discovered by Karl Ernst Claus in year 1844 in Russia. Ruthenium derived its name derived its name from from Ruthenia, the New Latin name for Russia
