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 Platinum was discovered by Antonio de Ulloa in year 1735 in Peru. Platinum derived its name derived its name from from the Spanish platina, meaning 'little silver'
