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 Bromine was discovered by Antoine Jérôme Balard in year 1826 in France. Bromine derived its name derived its name from from the Greek bromos, meaning 'stench'
