Bohr Atomic Model = Atom Analogy = Solar System (jan 1, 1913 – dec 31, 1913)
Description:
In 1913, the Danish scientist Niels Bohr proposed an improvement to the atomic model. He built on the concept that the mass of an atom is contained mostly in the nucleus. He also theorized that electrons move in definite orbits around the nucleus, much like planets circle the sun. In his model, these orbits, or energy levels, are located at certain distances from the nucleus.Added to timeline:
