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 Iodine was discovered by Bernard Courtois in year 1811 in France. Iodine derived its name derived its name from from French iode (after the Greek ioeides, 'violet')
