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 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'
