  • Oxygen is gas in room temperature. It has no colour and odour.Its symbol is 'O'.Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere.Oxygen is necessary for us to survive.
  • Oxygen was isolated by Michael Sendivogius before 1604, but it's commonly believed the element was discovered independently by Carl Wihelm Scheele. It's named by Antoine Lavoisier.
  • Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen,and most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms.
  • I can clearly feel that oxygen is disappearing. I am hardly to breathe. I know that I will die soon, and all the other living things will die too. If there're still people alive and read this note, I hope you can record it as human's history.I pray for the Earth.
