full_question: The English chemist John Mayow called an allotrope of this element spiritus nitroaereus after experiments he conducted with antimony, water, mice, and candles. This element was produced in experiments conducted by Pierre Bayen and by Robert Hooke, though they did not recognize its chemical form, instead hypothesizing that this element’s consumption was actually the release of (*) phlogiston. This element was first discovered by Carl Wilhelm Scheele, who called it “fire air,” and this element was given its modern name from the Greek for “acid producer” by Antoine Lavoisier because he incorrectly believed all acids contain this element. For 10 points, name this element which Priestly called “dephlogisticated air,” whose diatomic form makes up 21% of the atmosphere.
