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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'
