History

History
The element Sodium was discovered by Humphry Davy in year 1807 in United Kingdom. Sodium derived its name from from the English word soda (natrium in Latin)
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)
