Question

Given below are an Assertion (A) and a Reason (R). Assertion (A): The Bohr model is applicable to hydrogen and hydrogen-like atoms only. Reason (R): The formulation of the Bohr model does not include repulsive force between electrons. Choose the correct answer.

G1 Physics · Accepted Answer

The basic Bohr model treats a single electron moving under the electrostatic attraction of the nucleus. It does not account for electron-electron repulsion. Therefore it directly applies to one-electron systems such as hydrogen, He⁺, Li²⁺ and other hydrogen-like ions. Thus both Assertion and Reason are true, and the Reason explains why the model is restricted to hydrogen and hydrogen-like atoms. Correct option: B.
