History

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