Science question

As we all know there are some materials that emit no smell (like glass). Does this have to do with the fact that these materials emit no smell atoms (molecules?) to begin with or the fact that we don't have the correct smell receptors in our noses?

    Well, it's both. Solids like glass or metal don't release particles into the air so we can't smell them. Gasses like Carbon monoxide or oxygen are in the air but we don't have any receptors to detected them.
