Explain the difference between an orbit in the bohr model and an orbital in the quantum mechanical model of the atom. Rutherford's calculations show that the volume of the nucleus is very small compared to the total volume of the atom and the radius of an atom is about 10 -10 m, while that of the nucleus is 10 -15 m. Nuclear Model Of The Atom Based on his observations and conclusions, Rutherford proposed his model of the structure of the atom. 2)Rutherfords model do not deals with discrete energy levels. Bohr's model incorporated the then nascent quantum theory in that the distance between electron orbits was fixed, or quantized, and electrons traveling from one orbit to another absorbed or emitted these quanta of energy. In the Bohr model, the electrons' orbits are at fixed discrete distances from the nucleus, and in the Rutherford model, the orbits vary in their distance from the nucleus. The radius of the orbit depended on the amount of energy the electron had. The electrons were revolving around the central mass. He concluded that an atomic has specific, allowable energy levels called stationary states in which electrons occupy a fixed circular orbit around the nucleus. Also, the Bohr model established the relation between orbital size and energy of the orbitals which the Rutherford model couldnt. The other fundamental issue was the unexplained nature of the emission spectra of atoms. According to the theory, electrons travel in orbit shells around the nucleus. The line spectra of hydrogen atom had many discrete lines. Bohr's Model of an Atom Bohr's model consists of a small nucleus (positively charged) surrounded by negative electrons moving around the nucleus in orbits. There are a lot of similarities between the two models. What is Rutherford Model 4. (ii) According to Rutherfords model, the electrostatic attraction between electrons and the nucleus was likened to the gravitational force of attraction which implied the structure of a solar system.

Exercise 1.8.1 Calculate a value for the Bohr radius using Equation \(\ref{1.8.16}\) to check that this equation is consistent with the value 52.9 pm. Atoms with complete electron configurations are not active. The energy of an orbit is related to the size of the orbit. However, this Rutherford model of atom was also rejected because it couldnt explain why electrons and the positive charges in the nucleus are not attracted to each other. We can calculate an electronic transition energy the difference in energy between two allowed orbits with a straightforward formula: The Bohr model is good but not perfect. Comparison between Rutherford's model and Bohr's model: (i) Rutherford describes the atom as a tiny dense, positivity charged cored called a nucleus, in which nearly all the mats are concentrated. Complete Step by step solution: - Bohr's model of the atom was based on quantum theory where the electrons move around the nucleus in definite orbits.
