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 Ruthenium was discovered by Karl Ernst Claus in year 1844 in Russia. Ruthenium derived its name derived its name from from Ruthenia, the New Latin name for Russia |
