Question

Describe Rutherford's experiment of alpha particle scattering. What were the main observation of this experiment​

Answer 1

Answer:

Rutherford passed beams of alpha particles through a thin gold foil to observe the atom and noted how the alpha particles scattered from the foil.

Explanation:

Observation of Rutherford's alpha ray scattering experiment

1.Most of the alpha particles passed straight through the gold foil without any deviation.

2.Some of the alpha particles were deflected by the foil by some angles.

3.Interestingly one out of every 12,000 alpha particles appeared to rebound .

Good Morning

Have a nice day

Answer 2

Answer:

1. there is a positively charged core present inside an atom called nucleus.
2. all the mass of the is concentrated on nucleus.
3. the electrons revolve around the nucleus like planets revolving around the sun.
4. hence, Rutherford's model of an atom is called planetary-model of an atom.
5. atom is electrically neutral.
6. therefore,number of electrons = number of protons.
