A+ answer: A few of the alpha particles in his expeirment were deflected from the gold foil at large angles.
Scattering pattern of alpha particles 'shot' at a thin gold foil. Most went straight thru showing the nucleus was very small. Analysis of the scattering showed electrical repulsion, not that the particles actually hit the nucleus and bounced off.
The gold foil experiment convinced Ernest Rutherford that the atom has a small positively charged nucleus. In this experiment, alpha particles were shot at a thin gold foil. The fact that some of the alpha particles were deflected and even bounced back led Rutherford to conclude that atoms have a small, dense, positively charged nucleus.
Probably you refer to Ernest Rutherford.
Rutherford Discovered Many key factors of the atom. Especially about Protons and Electrons. He Did Not Know about neutrons. He Concluded That The atoms electron cloud was positive and electron floated around it like chocolate chips in a cookie.
Rutherford discovered the atomic nucleus and the proton.A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom.A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
Rutherford's experiments led to the discovery of the nucleus of an atom and the existence of protons within it. By conducting the famous gold foil experiment, Rutherford concluded that atoms have a small, dense, positively charged center containing protons.
In 1920, Rutherford gave the name proton to the positively charged particles in the nucleus of an atom.
the nucleus is positively charged because it bounces right off of the gold foil
protons
Ernest Rutherford explained the behavior of positively charged particles being deflected from metal foils as they interacted with the nucleus of the atom in his famous gold foil experiment. This experiment led to the discovery of the atomic nucleus as a small, dense, positively charged center within the atom.
Ernest Rutherford in 1919.

The gold foil experiment convinced Ernest Rutherford that the atom has a small positively charged nucleus. In this experiment, alpha particles were shot at a thin gold foil. The fact that some of the alpha particles were deflected and even bounced back led Rutherford to conclude that atoms have a small, dense, positively charged nucleus.
He discovered that an atom has a very dense and very tiny positively charged nucleus. He named the positively charged particles protons.
The Rutherford model was the model that showed the discovery of a positively charged nucleus. In this model, proposed by Ernest Rutherford in 1911, he suggested that atoms have a dense, positively charged nucleus at the center, with electrons orbiting around it. This model provided evidence for the nuclear nature of the atom.
According to scientist Rutherford, in the core of an atom is a positively charged nucleus and the nucleus is surrounded by negatively charged electrons.
