History	The element Barium was discovered by W. Scheele in year 1772 in United Kingdom. Barium derived its name from the Greek barys, meaning 'heavy'.	The element Oxygen was discovered by W. Scheele in year 1771 in Sweden and United Kingdom. Oxygen derived its name from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'.
