Here is your answer.........

⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️
➡️➡️➡️➡️➡️➡️➡️➡️Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogengroup on the periodic table, a highly reactivenonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. As compounds including oxides, the element makes up almost half of the Earth's crust.

oxygen is made of ----
*.Protons (8 of them)
*.Neutrons (Almost always 8 but 9 and 10 sometimes)
*.Electrons (8)
and according to chemistry expert ---
The oxygen gas that makes up 21% of our atmosphere is comprised of 2 oxygen atoms in a single oxygen molecule.Three oxygen atoms in a molecule is called Ozone; it is poisonous but the component of the upper atmosphere which protects the Earth from ultraviolet radiation.
I hope it helps U
