What are the primary atoms that make up the scents that we smell?

Molecules make scents. Aromatic ones (That is, containing rings of carbon atoms with delocalised electrons). Some unpleasant smells are due to hydrogen and sulphur groups.

Explanation:

Answer and Explanation:

These are really gas atoms which diffuse with air and spread aroma.

Aromatic compounds , otherwise called arenes or aromatics, are synthetic exacerbates that contain conjugated planar ring frameworks with delocalized pi electron mists rather than discrete exchanging single and double bonds.  

Natural mixes with C and H can smell lovely.  Compounds with nice aromas have no  direct link with scent, although many are known pleasant aromas.

Esters have pleasant smelling compounds and some of the foul smell arises as a result of the presence of sulphur or hydrogen groups.
