The main difference between Thomson and Rutherford model of atom is that Thomson model does not give details about the atomic nucleus whereas Rutherford model explains about the nucleus. Nearly a century later, Thomson introduced the newly discovered negatively charged electrons in his atomic model: with the "plum pudding mode,l" the atoms were finally divisible, but physicists were still a far shot from a realistic description of the atom. The Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. The atomic theory was further expanded upon in 1911 when Thomson's colleague Ernest Rutherford began experimenting with alpha particles to probe the atomic structure of gold foil. 2)Rutherfords model do not deals with discrete energy levels.

One electron can absorb or release energy from the outermost orbit shell. Niel Bohr's Atomic Theory states that - an atom is like a planetary model where electrons were situated in discretely energized orbits. The shell closest to the nucleus is . In 1913, Danish physicist Niels Bohr applied Max Planck's quantum theory to the nuclear atom of Ernest Rutherford, thus formulating the well-known planetary model of the atom, wherein electrons orbit a central nucleus in well-defined levels of energy ( Figure 1 ). It does not store any personal data. This model proposed that electrons are always traveling in specific shells or orbits around the nucleus. Smallest orbit has the lowest energy. Key Differences Between Bohr and Rutherford's Atomic Theory Given points are the critical one to understand the difference between two theories: Rutherford's theory says that in the center of an atom is a small positively charged nucleus, which is surrounded by negatively charged electrons. 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.
