History

History
The element Strontium was discovered by William Cruickshank (chemist) in year 1790 in United Kingdom. Strontium derived its name from from Strontian, a small town in Scotland
The element Manganese was discovered by Torbern Olof Bergman in year 1774 in Sweden. Manganese derived its name derived its name from corrupted from magnesia negra, see Magnesium
