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 Cesium was discovered by Robert Bunsen in year 1860 in Germany. Cesium derived its name derived its name from from the Latin caesius, meaning 'sky blue'
