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 Praseodymium was discovered by Carl Auer von Welsbach in year 1885 in Austria. Praseodymium derived its name derived its name from from the Greek praseios didymos meaning 'green twin'
