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 Fluorine was discovered by A.-M. Ampère in year 1810 in France. Fluorine derived its name from the Latin fluere, meaning 'to flow'.
