History

History
The element Tantalum was discovered by Anders Gustaf Ekeberg in year 1802 in Sweden. Tantalum derived its name from from King Tantalus, father of Niobe from Greek mythology
The element Oxygen was discovered by Carl Wilhelm Scheele in year 1774 in Sweden and United Kingdom. Oxygen derived its name derived its name from from the Greek word oxy-, both 'sharp' and 'acid', and -gen, meaning 'acid-forming'
