History

History
The element Platinum was discovered by Antonio de Ulloa in year 1735 in Peru. Platinum derived its name from from the Spanish platina, meaning 'little silver'
The element Helium was discovered by Pierre Janssen in year 1895 in Sweden and United Kingdom. Helium derived its name derived its name from from the Greek word helios, meaning 'sun'
