Assertion and Reason:
Assertion: Bohr had to postulate that the electrons in stationary orbits around the nucleus do not radiate.
Reason: According to classical physics, all moving electrons radiate.
Explanation:
Assertion: Bohr had to postulate that the electrons in stationary orbits around the nucleus do not radiate.
Reason: According to classical physics, all moving electrons radiate.
Explanation:
Bohr's atomic model, also known as the Bohr model, was proposed by Niels Bohr in 1913 as an improvement over the classical physics model of the atom. The classical physics model stated that any charged particle moving in a circular orbit would emit electromagnetic radiation. However, this contradicted the experimental observations of stable atoms.
Bohr's postulate:
To explain the stability of atoms, Bohr postulated that electrons in stationary orbits around the nucleus do not radiate energy. This postulate was necessary to reconcile the observed stability of atoms with the classical physics model, which predicted that the electrons would lose energy and spiral into the nucleus.
Reason as a correct explanation:
The reason provided, "According to classical physics, all moving electrons radiate," is a correct explanation for Bohr's postulate. In classical physics, any charged particle moving in a circular orbit accelerates and emits electromagnetic radiation. This phenomenon is known as radiation damping. However, Bohr's postulate suggests that electrons in stationary orbits do not radiate, which means they do not lose energy and spiral into the nucleus. This explanation aligns with the classical physics concept of radiation damping and provides a reason for Bohr's postulate.
Conclusion:
In conclusion, both the assertion and reason are correct, and the reason is a correct explanation of the assertion. Bohr's postulate was necessary to explain the stability of atoms by proposing that electrons in stationary orbits do not radiate energy, which is in accordance with the classical physics concept of radiation damping.

Bohr postulated that electrons in stationary orbits around the nucleus do not radiate. This is the one of Bohr’s postulates, According to this the moving electrons radiate only when they go from one orbit to the next lower orbit.
