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 Lanthanum was discovered by Carl Gustaf Mosander in year 1839 in Sweden. Lanthanum derived its name derived its name from from the Greek lanthanein, meaning 'to lie hidden' |
