The Bohr-Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. What is the main difference between the Bohr model and earlier models The Rutherford Model shows an atom with electrons orbiting a fixed, positively charged nucleus in set, predictable paths. Rutherfords model states that most of the atom consists of an empty space and the center of the atom contains a positively charged nucleus surrounded by negatively charged electrons, resulting in continuous electron spectrum. what are the differences between the Rutherford and Bohr models of the atom?

In this experiment, a very thin gold foil was bombarded with a beam of alpha particles. The main difference between Bohr model and Rutherford model is that in Rutherford model, electrons can revolve in any orbit around the nucleus, whereas in Bohr model, electrons can revolve in a definite shell. Because of such limitations in Rutherfords model, the Danish physicist Niels Bohr proposed a new model in 1913 based on the quantum theory of radiations.
