The Rutherford atomic model, sometimes called the planetary model of the atom, describes the atom as taking which configuration? Correct Answer a dense, positively charged nucleus orbited by light, negatively charged electrons
Proposed in 1911 by the British physicist Ernest Rutherford, the Rutherford atomic model postulates the nucleus to be small and dense. The negative electrons that balance electrically the positive nuclear charge are regarded as traveling in circular orbits about the nucleus. The electrostatic force of attraction between electrons and nucleus is likened to the gravitational force of attraction between the revolving planets and the Sun. This model is thus also called the planetary model of the atom.
