atom is empty. Some particles were scattered at a large angle, and very few of them scattered back in the direction from which they had come. Based on these
observations, Rutherford proposed an atomic model, which is known as Rutherford’s atomic model.

Conclusions from Rutherford’s experiment
Watch the animation depicting Rutherford’s experiment and choose which of the following conclusions are correct.
Check all that apply.
In Rutherford’s experiment, he bombarded positively charged
particle from a radioactive source onto thin gold foil. The foil was surrounded by a
sheet of fluorescent material (zinc sulfide
sheet lit up when it was hit with
particles. The image below shows the scattering of
particles. The circular green spots on the fluorescent screen are formed when the
particles hit the screen.
By looking at the number of
particles that scattered at different angles from the gold foil, Rutherford proposed an atomic model, which is known as
Rutherford’s atomic model.
The image given below explains the molecular view of the scattering of
particles from the gold foil.
