Is the mixture of gases in the atmosphere considered a solution suspension or a colloid?

Answer 1

The mixture of gases in the atmosphere are a solution of gases. Since nitrogen makes up 78% of the gases in the atmosphere, it is the solvent and the other gases are the solutes.

Answer 2

The mixture of gases in the atmosphere is not considered a solution, suspension, or colloid because gases are uniformly distributed and do not form distinct phases in the atmosphere. It is more accurately described as a homogeneous mixture of gases known as air.
