There is no chemical formula for air as it is a mixture of many different compounds with varying percentages thereof. The major components would be Nitrogen( N2), Oxygen( O2), Carbon Dioxide( CO2), Water( H2O), and many others in minute amounts.
WHY IS THE AIR
INVISIBLE?
By Matt Cardoso
T he atmosphere is composed of colorless gases. So to see any gas, it must have some color. This only happens when its chemical elements absorb visible light, like the rain-bow in which each of the seven light rays corresponds to a different color. This is how it works: When the atoms of a gas are hit by light they retain some rays. If the particles absorb it, for example, a yellow radius, the pitch of the vapor is set by admixture of the colors of the rays that are left- in this case we would see a purple gas( Amazing!). But not all rays that make up light are visible- and the ones that we can’ t see are the ones that the air absorbs. Nitrogen and oxygen- which make up 99 % of the atmos-phere, only retain the invisible ultraviolet rays.
So, like all the colors we see crossing the air, it remains transparent.“ If the atmosphere was formed, for example, by a gas such as iodine vapor, which absorbs visible colors, the air would be violet,” says chemist Edvaldo Sabadini, Unicamp. Just imagine it!!!!
