History

History
The element Cadmium was discovered by Karl Samuel Leberecht Hermann in year 1817 in Germany. Cadmium derived its name from from the New Latin cadmia, from King Kadmos
The element Silicon was discovered by Jöns Jacob Berzelius in year 1824 in Sweden. Silicon derived its name derived its name from from the Latin silex, 'flint' (originally silicium)
