Bohr model utilized the existing knowledge of the nucleus derived from the Rutherford model. In physics the Bohr Model, still commonly used and taught today because of its simplicity, depicts the atom as a small positively charged nucleus with electrons in orbit at different levels, similar in structure to the solar system. It does not explain the Zeeman Effect. The nucleus is positively charged and the electron orbit around the nucleus. And he thought that atoms looked like Billiard Balls. It does not give a clear description about the spectra for larger atoms. This gave Rutherford an implication of scattered electrons around the nucleus which is called electron clouds. Her interest areas for writing and research include Biochemistry and Environmental Chemistry. The Rutherford model suggested the positive charge of the atom was concentrated inside the center of the atom. an electron revolving around the nucleus in an atom. Rutherford had discovered the nuclear atom, a small, positively-charged nucleus surrounded by empty space and then a layer of electrons to form the outside of the atom. It was also found that one out of every 12000 particles appeared to rebound. Bohr model suggested that the electrons of an atom traveled in circular orbits around the central nucleus. The Bohr Model provides an incorrect value for the ground state orbital angular momentum. Energy Levels: Rutherfords model does not deal with detached energy levels besides the Bohr model describes detached energy levels.
