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 Barium was discovered by Carl Wilhelm Scheele in year 1808 in United Kingdom. Barium derived its name derived its name from from the Greek barys, meaning 'heavy'
