∙ 8y agoOxygen is the main gas present in air.
Atmospheric chemistry is composed primarily of nitrogen (N2) at about 78%, almost 21% is oxygen (O2), less that a percent is argon (AR), and the remainder is composed of trace amounts of carbon dioxide (CO2), neon (Ne), helium (He), methane (CH4), krypton (Kr), and hydrogen (H2), and isotopes of all of these. Water vapor generally makes up about 1%, but that level can vary. There can also be a number of pollutants in the air at any one time such as carbon monoxide, cadmium, benzene, arsenic, cyanide, Mercury, and ozone as well as a nearly limitless list of other contaminants.

21% oxygen
almost 1% argon
the rest .000000001% is a bunch of other gases

Oxygen- 21%
Hydrogen- 4%
Other gases (Argon,Neon, Helium..)- 1%

Why silver turns black on exposure to air?
Sulphur and Nitrogen dioxide and trioxide gases present in the air, as pollutants, react with the surface of the silver to form black compounds such as Silver nitrate and Silver sulphide.

Is water present in air?
Aside from bubbles, there is no "air" in water, however oxygen and other atmospheric gases, such as oxygen or nitrogen, may readily absorb into water. Water is after all made up of two atmospheric gases, hydrogen and oxygen.
When we breathe in we inhale many gases present in the air including oxygen what do you think happens to the gases that are not needed by the body?
Nothing - they are "breathed out" with your exhale.
