In order to understand why you cannot see an atom with the naked eye, you must understand what it means to see something.
We see objects when light comes off those objects. The objects you encounter in your everyday life are made of billions and billions of atoms and
molecules. Each atom or molecule emits light as its electrons go from an excited energy level to a lower energy level. When you see an object, you
are seeing the billions and billions of photons that are emitted by that objects molecules and atoms.
Light does not come off an atom the way it comes off an object you encounter in your everyday life. An atom may emit light, but the components of an
atom like its electrons, protons, and neutrons do not emit light in an of themselves.
