History

History
The element Silicon was discovered by Jöns Jacob Berzelius in year 1824 in Sweden. Silicon derived its name from from the Latin silex, 'flint' (originally silicium)
The element Indium was discovered by Ferdinand Reich in year 1863 in Germany. Indium derived its name derived its name from from indigo
