Question

How was Bohr’s atomic model different from Rutherford’s atomic model?

Answer 1

• Rutherford model suggested a new look into the nature of the nucleus, whereas the Bohr model suggested a new look into the mechanics of electrons.

• Bohr model utilized the existing knowledge of the nucleus derived from the Rutherford model.

• Rutherford model is based on the experiments Rutherford conducted in collaboration with Geiger and Marsden. The Bohr model is based on existing experimental results.

Answer 2

Answer:

C.  

Bohr’s model showed that electron orbits had distinct radii.

Explanation:

Bohr’s atomic model stated that electrons move in definite orbits. Electron shells are quantized. Electrons could move in the 1st, 2nd, 3rd shell etc. As electrons move in definite orbits they are at distinct distance from the nucleus. Thus each orbit has a distinct and different radii from the nucleus of the atom.
