Oxygen is the 8th element on the periodic table, with an atomic number of 8 and atomic mass of 15.9994. It is commonly found in the atmosphere, oceans, and sun. Oxygen does not burn itself but supports combustion in other substances, making it useful in hospitals to destroy bacteria. Oxygen was discovered in 1774 by Joseph Priestly and Carl Wilhelm Scheele through experiments observing gases produced from substances like red hot manganese oxide.

6. Oxygen is commonly found in the atmosphere,
sun,and the ocean

7. Oxygen is commonly used in hospitals.
It is appropriate for this use because it destroys
bacteria.

8. Five compound oxygen can be found in:
water (h20) - naturally made
lithium oxide (li2o) - naturally made
hydrogen peroxide (h2o2) - naturally made
carbon dioxide (co2) - man made
oxygen difluoride (of2) - both man made &
naturally made

9. Oxygen was discovered in 1774 by Joseph Priestly & Carl
Wilhelm Scheele. Oxygen was discovered when Carl
Scheele was doing an experiment, he saw that red hot
manganese oxide could produce gas. Oxygen was then
identified as oxygen in 1775 when a different scientist did
more experiments.

10. Oxygen does not burn, but it does support
combustion in other substances.
