Question

1. Explain, in detail, how the Bohr model was an improvement over the Rutherford nuclear
model of the atom.

Answer 1

To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy. The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another.
