History

History
The element Oxygen was discovered by Carl Wilhelm Scheele in year 1774 in Sweden and United Kingdom. Oxygen derived its name from from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'
The element Samarium was discovered by Lecoq de Boisbaudran in year 1879 in France. Samarium derived its name derived its name from from Samarskite, the name of the mineral from which it was first isolated
