through this he proved that
1 most of the space inside an atom was empty
2 very few alpha radiations got deflected thus the positive sphere was very small
positive
Rutherford proved it it from his alpha-particle scattering experiment.
The alpha radiation in the experiment was detected by using a microscope and a fluorescent screen. When an alpha particle strikes the screen, the coating will fluoresce, and it will give off a "flash" of light. This small flash of light can be picked up by the investigator using the microscope.
An alpha particle is a helium nucleus; it has a charge of +2.
The charge of an alpha particle is 2+ and the symbol is α2+.
positive
he shot tiny alpha particles throug a piece of gold foil.

A zinc sulfide coated screen surrounding the gold foil produced a flash of light whenever it was struck by an alpha particle. By noting where the flash occurred, the scientists could determine if the atoms in the gold foil deflected the alpha particles.
Some alpha particles deflected, some went straight through and come were deflected.
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
positive
Rutherford proved it it from his alpha-particle scattering experiment.
The first ever experiment this fact was the alpha particle experiment which was conducted by Rutherford. In this experiment, alpha particles are positive charged substances and they were repulsed with the nuclei in the golden foil.
Rutherfords experiment proved the existence of a nucleus as some alpha particles "bounced back" from the gold foil sample . Thomson model did not involve a nucleus and predicted just a slight deflection or none at all.
There are 2 neutron in an alpha particle.
