History

History
The element Magnesium was discovered by Joseph Black in year 1755 in United Kingdom. Magnesium derived its name from from Magnesia, a district of Eastern Thessaly in Greece
The element Argon was discovered by Lord Rayleigh in year 1894 in United Kingdom. Argon derived its name derived its name from from the Greek word argos, meaning 'idle'
