Ernest Rutherford used alpha particles to bombard a thin gold foil. In the early 1900's, particle accelerators were new and worked on the same principle as the old TV sets (before the plasma and LED ones we have now)
The alpha particle was emitted from radium bromide in to a vacuum tube with a large electric field applied. The alpha, with charge = +2 electrons, was accelerated in the electric field and made to hit the gold foil. By looking at the ways the alpha particles bounced off the foil, Rutherford formulated a model of the atomic structure more or less as we know it today - A dense nucleus and electrons floating around the outside. Basically, the vast majority of the atom volume is vacuum.
He didn't use protons because there is no radioactive substance which emits protons. Only alpha emiitters (2p + 2n), beta elecron/positron emitters and gamme (high energy light) emitters exist naturally.

What is a positively charged subatomic paricle?
The proton is a positively charged subatomic particle
How Rutherford's experiment led to structure of atom?
Rutherford found that there was a dense center to an atom.
Who was given credit for discovering the proton?
Ernest Rutherford is credited with the discovery of the proton.
What is the scattering experiment?
The scattering experiment of E. Rutherford and his team lead to the disvovery of the proton and to a new atomic model. Alpha particles colliding an atom are scattered by the positive atomic nucleus containing protons.
Which subatomic particles has a charge?
This particle is the electron with the electrical charge -1.
What contribution experiment and reasons of Ernest Rutherford?
E. Rutherford discovered the proton.
What is the positive particle that Rutherford said carried the positive charge in the nucleus of an atom was named?
This particle is the proton.
What part of the nucleus did Rutherford add to the atom model?
He added the proton. He thought that the only particle in the nucleus was the proton. The neutron was discovered much later by Chadwick.
What particle did Rutherford discover?
Through his gold foil experiment, Rutherford identified the nucleus and believed it to be compact but containing the majority of the atom's mass, and the electron cloud. He figured this out based on the deflection of the alpha particles, which rarely hit the nucleus, but sometimes would hit it and deflect at high angles.
What is a positively charged subatomic paricle?
The proton is a positively charged subatomic particle
What particle did Ernest Rutherford discover?
In 1911, Ernest Rutherford discovered the nucleus of the atom. Rutherford was born in New Zealand in 1871 and became known as the father of nuclear physics.
What did the rutherford's gold foil experiment show?
The alpha particules went straight threw the gold foil
Who invented the proton?
Ernest Rutherford is generally credited with the discovery of the proton
What nuclear atom did Rutherford discover?
Through the Gold Foil Experiment, he discovered that when Gold Atoms were deflected off of tin foil, some of them must have bounced. He noticed this because of a dense center in the atoms, which he noted to be the nucleus. Because of this, he is considered the discoverer of the nucleus. he had a 1cher he was a dick thanks did I help?

Ernest Rutherford
How Rutherford's experiment led to structure of atom?
Rutherford found that there was a dense center to an atom.
Who discovererd the proton?
Rutherford
