Assertion: Rutherford atomic model failed to explain the stability of an atom.
Reasoning: According to Rutherford's atomic model, electrons revolve around the nucleus in circular orbits, but such an arrangement would lead to the acceleration of electrons and ultimately cause the atom to collapse.
Both assertion and reasoning are true, and the reasoning is the correct explanation of the assertion.
Both assertion and reasoning are true, but the reasoning is not the correct explanation of the assertion.
Assertion is true, but the reasoning is false.
Assertion is false, but the reasoning is true.
Answers (1)
Correct Option a) Both assertion and reasoning are true, and the reasoning is the correct explanation of the assertion.
According to Rutherford's atomic model, the electrons revolve around the nucleus in circular orbits, similar to planets orbiting around the sun. However, the model could not explain why the electrons did not emit energy continuously and eventually fall into the nucleus. In classical mechanics, any charged particle undergoing acceleration emits radiation, which causes the particle to lose energy, ultimately causing it to spiral into the nucleus. This limitation was resolved by the development of quantum mechanics, which explained that the electrons exist in discrete energy levels and not in fixed orbits.
