ANSWER:
Oxygen was discovered by two chemists working independently. They were Carl Scheele of Sweden and Joseph Priestley of England. Scheele's laboratory notes show that he prepared oxygen in the early 1770's by heating various compounds, including saltpeter, and mercuric oxide. But Scheele's experiments were not published until 1777. Priestley also published his experiments in 1777. He described how he prepared oxygen by heating mercuric oxide.
Scheele called oxygen "fire air." Priestley called it "dephlogisticated air." In 1777, the French chemist Antoine Lavoisier named the gas oxygen.

∙ 14y agoOxygen was independently discovered 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 publication came out in print first. The name oxygen was coined in 1777 by Antoine Lavoisier.
