Question

How is atom and molecules related to our sense of smell?

Answer 1

Humans detect smell by inhaling air that contains odor molecules, hence, bind to receptors inside the nose, relaying messages to the brain. Most scents are composed of many odorants, for example, a chocolate is made up of hundreds of distinct odor molecules

Answer 2

Answer:

Atoms themselves do not have a smell. Molecules do.

Explanation:

What happens is that particular molecules bind to receptors in our nose, activating nerves, that then send signals to our brain, which we then interpret and perceive as “smells”. Different molecules bind to different receptors, which is why we can perceive a number of different smells
