WebThe Bohr model of the atom proposed by Neils Bohr is similar to the planetary motion. Hence this model is also known as the planetary model of the atom. He describes that the negatively charged electrons will orbit around the positively charged nucleus. Similar to the gravitational force of attraction between the sun and the planets, in the ... WebThe model was proposed by physicist Niels Bohr in 1913. In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells. The model is also referred to as the planetary model of an atom. The electrons orbit around the nucleus similar to how planets orbit around the sun.
