original question: Who discovered [Oxygen] and another chemical element with the largest electronegativity (pauling scale)?
answer: carl wilhelm scheele
answer type: Chemical Element Discoverer.
auxiliary information: Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element and oxidizing agent that readily forms compounds with most elements. Photosynthesis releases oxygen, and respiration consumes oxygen. Changes in phosphate are related to changes in oxygen concentrations. Oxygen was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first. The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion. Its name derives from the Greek roots ·ΩÄŒæœçœÇ oxys, "acid", literally "sharp", referring to the sour taste of acids and -Œ≥ŒµŒΩŒÆœÇ -genes, "producer", literally "begetter", because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition.
