yes, it forms about 21% of our atmosphere.
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier

Oxygen is an element. At room temperature, molecular oxygen (O2) is a gas.
The molecular weight of O2 (oxygen gas) is approximately 32 g/mol.
Oxygen gas is considered heavier than other gases (like nitrogen and helium) because the oxygen molecule (O2) has a higher molecular weight due to its two oxygen atoms bonded together. This higher molecular weight causes oxygen gas to be denser and therefore heavier than some other gases.
Molecular oxygen makes up 42% of Mercury's atmosphere.
Yes, oxygen is a pure element that has atoms. However, the allotrope dioxygen (O2) is what we breathe, a molecular form of 2 oxygen atoms. Similarly, the gas ozone (O3) is a molecular combination of 3 oxygen atoms that has greatly altered properties.
The molecular equation for the combustion of methane gas (CH4) in the presence of oxygen (O2) is: CH4 + 2O2 -> CO2 + 2H2O.
Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
Oxygen (1,429 g/cm3) is more dense than ammonia (o,70 g/cm3).
Oxygen can be a solid, liquid, or gas, depending on the temperature and pressure and on what other elements it is bound to in a chemical compound. Free molecular oxygen, as found in the Earth's atmosphere, is a gas. Oxygen bound with hydrogen in the Earth's oceans is a liquid. Oxygen bound with iron in iron oxide (rust) is a solid.
Cyanobacteria make molecular oxygen in our atmosphere.
