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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'
