History	The element Magnesium was discovered by J. Black in year 1755 in United Kingdom. Magnesium derived its name from Magnesia, a district of Eastern Thessaly in Greece.	The element Iodine was discovered by B. Courtois in year 1811 in France. Iodine derived its name from French iode (after the Greek ioeides, 'violet').
