Difference Between Rutherford’s Model and Bohr’s Model

A brief article on the difference of the atomic models made by Ernest Rutherford and Niels Bohr.

Rutherford describes the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated. He confirmed the existence of proton. He pictured in his model that electrons are in motion around the nucleus. According to Rutherford’s model, electrons may move anywhere within the volume of space around the nucleus. This concept contradicts with the atomic model that was later proposed by Niels Bohr. Bohr made restrictions to the movement of electrons by imposing pictures of electrons in an orbit around the nucleus. In his theory, he used the quantum rule which was introduced by Max Planck.

According to Rutherford’s 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. This gave Rutherford an implication of scattered electrons around the nucleus which is called electron clouds. However, Bohr gave Rutherford’s atomic model a shell structure in which electrons corresponds to specific orbits with a discrete energy level. He concluded that an atom has specific, allowable energy levels called stationary states in which electrons occupy a fixed circular orbit around the nucleus. He fixed and approximately located presence of electrons in orbital surrounding a nucleus by using quantum mechanics principles.

    nice article. very informative. but even science evolves. definitions and theories will soon be much deeper or even proven.

    strange point.orbits in my book are mentioned in rutherford model as well.so its a similarity rather than a difference
