Question

state the three observations made by Rutherford on his particle scattering experiment​

Answer 1

Conclusions drawn

1. The revolution of the electron in a circular orbit is not expected to be stable.

2. Any particle in a circular orbit would undergo acceleration. During acceleration, charged particles would radiate energy.

3. Thus the revolving electrons would lose energy and finally fall into the nucleus.

4. The atom should be highly unstable and hence matter would not exist in the form.

Features of nuclear model

1. There is a positively charge centre in an atom called nucleus. Nearly all the mass of an atom resides In the nucleus.

2. The electrons revolve around the nucleus in circular paths.

3. The size of the nucleus is very small as compared to the size of the atom.

I hope u got your answer.
