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 Bismuth was discovered by Claude François Geoffroy in year 1400 in unknown place. Bismuth derived its name derived its name from from German word, now obsolete
