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 Beryllium was discovered by Louis Nicolas Vauquelin in year 1797 in France. Beryllium derived its name derived its name from from beryl, a mineral
