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 Indium was discovered by Ferdinand Reich in year 1863 in Germany. Indium derived its name derived its name from from indigo
