The Bohr model is still commonly taught today as the basis for modern atomic theory. In modern atomic theory, an atom is a group of particles that is joined together by two different forces.

In fact, photons are the onlythings that humans can directly see. A photon is a bit of light. Human eyes are specifically designed to detect light. This happens when a photon enters the eye and is absorbed by one of the rod or cone cells that cover the retina on the inner back surface of the eye.
