Question

What were the features and drawbacks of Rutherford's atomic model ?

Answer 1

The significant features of Rutherford's Atomic model :-

1. All protons are present inside the nucleus, which is situated at the center of the atom.

2. Electrons are located outside the nucleus and revolve around it in well-defined orbits.

3. The size of the nucleus is very small, in comparison with the size of an atom. As per Rutherford’s calculations, the size of the nucleus is 10^5 times smaller than an atom.

4. As the mass of the electron is negligible compared to the mass of the proton, almost all the mass of the atom is concentrated in the nucleus.

The drawbacks of Rutherford's Atomic model :-

a. Rutherford's Atomic model is applicable only to electron-type atoms.

b. According to Rutherford, as the electron revolves around the nucleus it liberates energy on a regular basis. So, when the electron looses all its energy it should fall in the nucleus, which is impossible to occur.
