Question

Write any three features of Rutherford's nuclear model of an atom.

Answer 1

The major features of the model are as follows.

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

2. Electrons reside outside the nucleus and revolve around the nucleus in well-defined orbits.

3. The size of the nucleus is very small in comparison to the size of an atom. As per Rutherford’s calculations, the size of the nucleus is 105 times smaller than an atom.

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

hope this helps you....:)

Answer 2

Hi ,
here is your answer:

i) There is a positively charged centre in an atom called the nucleus. Nearly, all the mass of an atom resides in the nucleus.

ii) The size of the nucleus i.e., 10-15m is very small compared to the size of the atom (i.e., 10-10 m).

iii) The electrons rotate around the nucleus in well-defined orbits.
