text: ```Oxygen na one chemical element wey get symbol O and atomic number 8. E dey belong to the chalcogen group for di periodic table and e be one highly reactive nonmetal and oxidizing agent wey dey easily form compounds (especially oxides) with most elements. By mass, oxygen na di third most abundant element for di universe, after hydrogen and helium. At standard temperature and pressure, two atoms of di element dey bind to form dioxygen, wey be colorless and odorless diatomic gas with di formula O 2. Diatomic oxygen gas make up 20.8% of di Earth's atmosphere. However, monitoring of atmospheric oxygen levels dey show say global levels dey reduce, because of fossil-fuel burning. Oxygen na di most abundant element by mass for di Earth's crust as part of oxide compounds like silicon dioxide, wey dey make up almost half of di crust's mass.

Many major classes of organic molecules for living organisms, like proteins, nucleic acids, carbohydrates, and fats, contain oxygen, as well as di major inorganic compounds wey dey make up animal shells, teeth, and bone. Most of di mass of living organisms na oxygen as e dey part of water, wey be di major constituent of lifeforms. Oxygen dey used for cellular respiration and e dey released by photosynthesis, wey dey use di energy of sunlight to produce oxygen from water. E dey too chemically reactive to remain as a free element for air without continuous replenishment by di photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O 3), dey strongly absorb UVB radiation and as a result di high-altitude ozone layer dey help protect di biosphere from ultraviolet radiation, but e dey pollute near di surface where e dey as a by-product of smog. For even higher low earth orbit altitudes, enough atomic oxygen dey present to cause erosion for spacecraft.

Answer di following questions:
1. Wetin di article dey about?
2. Wetin be di symbol?
3. Wetin be di numeral?
4. E dey abundant?
5. How e dey rank?
6. Wetin dey more abundant?
7. Wetin make up O2?
8. Wetin dey reduce earth levels of O2?
9. O2 dey inside our planet?
10. How plants dey release O2? Wetin be di process?
11. Wetin be O3?
12. Where dem dey find am?
13. E dey near di face of di planet?
14. Wetin dem dey call am?
15. Smog dey cause am?
16. Wetin fit erode space vehicles?
17. At wetin level?
