History

History
The element Radium was discovered by Pierre Curie in year 1898 in France. Radium derived its name from from the Latin radius, 'ray'
The element Strontium was discovered by William Cruickshank (chemist) in year 1790 in United Kingdom. Strontium derived its name derived its name from from Strontian, a small town in Scotland
