Nitrogen
Argon
Carbon

Helium
and a lot more! Some other gases are Nitrogen, Argon, Neon, and Hydrogen.
Humans have evolved to respire oxygen because it is essential for producing energy in our cells. Other gases do not support this process, so breathing gases other than oxygen would not provide the necessary energy for our bodies to function properly. Breathing other gases, such as nitrogen or carbon dioxide, can actually be harmful or fatal to humans.
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.
Some common gases other than water vapor include oxygen, carbon dioxide, nitrogen, helium, and methane. These gases are essential to Earth's atmosphere and play various roles in supporting life and maintaining the planet's climate.
oxygen, nitrogen, hydrogen, fluorine
Nitrogen rhen oxygen then argon and less than 1% of other gases
nitrogen & oxygen
Living plants only produce oxygen. Dead plant matter, when it decays, can produce methane, hydrogen sulfide, and other interesting gases.
Approximately 1% of Earth's atmosphere is made up of gases other than oxygen and nitrogen, including argon, carbon dioxide, and trace amounts of gases like helium, neon, and methane.
Methane and Oxygen
roughly 80% is nitrogen, 19% is oxygen. There are also small quantities of other gases etc.
About 78% of Earth's atmosphere is nitrogen, while about 21% is oxygen. This leaves only around 1% for other gases such as argon, carbon dioxide, and trace gases like methane and water vapor.
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.
