Question

Does wind have atoms and molecules in it?

Answer 1

Wind can have atoms and molecules from pollen and spores from plants and fungi.

Answer 2

Of course. Wind is air in motion, and the gases in air are composed of
all the usual familiar stuff ... atoms, molecules, mass, etc. That's how
the wind moves things ... it has momentum and kinetic energy, which
get transferred to the things that move in the wind.
