Atomic Models: We are all aware that everything in our environment is made out of matter.We also know that electrons, protons, and neutrons are the three subatomic particles. Rutherford Model: Rutherford model does not explain the relationship between orbital size and the energy of the orbital. . Rutherfords atomic model says that an atom is composed of a core. Rutherford explained the nucleus of an atom and Bohr modified that model into electrons and their energy levels. 2. How is Bohr's atomic model similar from Rutherford's? These shells have discrete energy levels. Orbi in Bohr's model are specific circular paths, while an orbital in the quantum mechanical model has electron clouds that have a 90% of finding an electron.

Comparison between Rutherfords model and Bohrs model: (i) Rutherford describes the atom as a tiny dense, positivity charged cored called a nucleus, in which nearly all the mats are concentrated. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump. He kept the positively charged nucleus part the same but he further defined the negatively charged space surrounding it as electrons of tiny comparative mass that orbit the central core in defined rotational orbits similar to the solar system (planets around the Sun). Reference: 1. It does not offer an explanation of the relationship between orbital size and energy. How did Bohr change Rutherford's model of the atom? Thomsons plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged soup. Rutherfords gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Smallest orbit has the lowest energy. The Bohr Model does not explain fine structure and hyperfine structure in spectral lines. 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. The orbital model for atoms fixed many of these shortcomings. Describe the presence of discrete energy levels.

Bohr model was proposed by Niels Bohr in 1915. There are a lot of similarities between the two models. Bohr model explains the bond between orbital size and the energy of the orbital; negligible orbital has the lowest energy. Orbits are stationary to provide a fixed circular path, Each orbit has a certain amount of energy and size, The energy of the orbit is correlated to its size, Radiation is either emitted or absorbed by electrons moving around the orbit shells. Rank the following items in order from largest to smallest: cell, chromosome, gene, DNA, organism, nucleus. It also fails to explain many spectral lines associated with marginal atomic phenomena. Rutherford said that electrons revolve around the nucleus in rings. It cannot predict the relative intensities of spectral lines.
