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 Iodine was discovered by Bernard Courtois in year 1811 in France. Iodine derived its name derived its name from from French iode (after the Greek ioeides, 'violet')
