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 Yttrium was discovered by Johan Gadolin in year 1794 in Finland. Yttrium derived its name derived its name from from Ytterby, Sweden
