Why is air invisible?

Our atmosphere is made up of colorless gases and, as we know, they are invisible. To see a gas, it needs to have some color. This is only possible when its chemical elements absorb light, since, like the rainbow, each of its rays compose light of a different color. The fact is that when the atoms of any gas are hit by light, they _______ some of the rays. If the particles absorb a yellow ray, for example, the color of the vapor will be the result of mixing the remaining colors of the rays – in this case, purple. It turns out that not all rays are visible, including the one that the air absorbs. Nitrogen and oxygen – 99% of the atmosphere – only retain invisible ultraviolet rays. So, as colors pass through the air, it is transparent.
