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 Antimony was discovered by unknown in year 3000 BC in unknown place. Antimony derived its name derived its name from from the Greek anti, 'against', and monos, 'alone' (stibium in Latin)
