Bohr model in atomic physics, the bohr model, devised by niels bohr, depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus&mdashsimilar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity. Tim and moby discuss how electrons and neutrons were discovered, what atoms are made of, and how long it took to create an atomic model.
