Explanation:
Oxygen is a chemical element with an atomic number of 8 (it has eight protons in its nucleus). Oxygen forms a chemical compound (O2) of two atoms which is a colorless gas at normal temperatures and pressures.
Oxygen atoms are very reactive, and are incorporated into many common chemical compounds, such as water (H2O), carbon dioxide (CO2), carbon monoxide (CO), sulfur oxides (SO2 and SO3), and nitrogen oxides (NO and NO2).
About 21% of Earth's atmosphere is oxygen. This hasn't always been the case, though. Early in our planet's history, the atmosphere had almost no oxygen. Microbes that produce their food via photosynthesis generate oxygen as a by-product. Oxygen from photosynthetic microbes eventually built up in the atmosphere, drastically changing our planet's environment and the history of life in the process.
