Oxygen
| Basic: |
| Oxygen is a type of non-metallic element. |
| Documentation: |
| Comment: A piece (i.e., specific collections of nearby molecules) of #$Oxygen in stuff form. |
| Miscellaneous: |
| Types of oxygen include O3, O2-, and O2. When oxygen is found in the atomic composition of dioxygen, its oxidation number is 0. When oxygen is found in the atomic composition of peroxide, its oxidation number is -1. |
| All oxygen has the density 1.43 grams per liter. The boiling point of all oxygen is -182.962 degrees Celsius. Every oxyphobic anaerobic bacterium can be killed by exposure to oxygen. No aerotolerant anaerobic bacteria can be killed by exposure to oxygen. |
| -2 and 1 are possible oxidation numbers for oxygen. |
| Some oxygen was used and somehow altered in all respiration. Some oxygen got inhaled in all inhalation of oxygen. If some inhalation of oxygen is inhalation of oxygen and some X got inhaled in that inhalation of oxygen, then X must be oxygen. |
| The atomic number of oxygen is 8. A possible valence of oxygen is -2. |
| The atomic weight of oxygen is 15.9994 atomic mass units. Oxide ions are an ion of the element oxygen. |
