enlist the conclusions drawn by Rutherford from his x-ray scattering experiment

HELLO YOUR ANSWER IS GIVEN BELOW
Answer:
CONCLUSION DRAWN BY THE EXPERIMENT-:
- As most of the alpha particles passed through the gold foil were undefelected, it suggest that most of the space in an atom is empty.
- As few particles were deflected, and this deflection will be due to very strong repulsive force caused by a positive charge. It shows that the positive charge is not spread throughout the atom. In fact it is densely concentrated to an extremely small region called nucleus.
- Calculation by Rutherford shows that the nucleus is 100000(10 raised to power 5) times smaller than atom.

ANSWER
Rutherford concluded from the α-particle scattering experiment that:–
(i) Most of the space inside the atom was empty because most of the α-particles passed through the gold foil without any deflection.
(ii) Very few particles were deflected from their path, indicating that the positive charge occupied very little space inside the atom.
(iii) A very small fraction of α-particles were deflected by 180
o
, indicating that the positive charge and the mass of the gold atom is concentrated in a very small volume within the atom.
From the data, he also calculated that the radius of the nucleus was about 105 times smaller than the radius of the atom.
