What else can I help you with?
An experiment using alpha particles to bombard a thin sheet of gold foil indicated that most of the volume of the atoms in the foil is taken up by?
a small, dense, positively charged nucleus. This led to the discovery of the atomic nucleus and the development of the nuclear model of the atom.
What is the explanation for the scattering experiment of Rutherford?
Rutherford conducted an experiment in which Alpha particles were fired at a gold nucleus. Most of the particles passed through unaffected. However, some were deflected by a small amount whilst an even smaller number of the particles were deflected completely. This led to the conclusion that the atom has an extremely small, central, positively charged nucleus. As both the positive alpha particle and the positive nucleus repel each other by electrostatic forces. The fact that only a small amount of particles are deflected shows that the nucleus is only a tiny central part of the atom.
What subatomic particle did the gold foil experiment discover?
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
Who discovered the nucleus using his gold foil experiment?
Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.
How was Rutherford theory proven?
Rutherford's theory that atoms have a small, positively charged nucleus was proven through the famous gold foil experiment. In this experiment, alpha particles were shot at a thin gold foil, and some particles were deflected back, suggesting a small, dense nucleus within the atom. This experiment provided strong evidence for the nuclear model of the atom.

What bounced back in Rutherford's gold foil experiment?
Alpha particles bounced back in Rutherford's gold foil experiment. This observation led to the conclusion that atoms have a small, dense nucleus at their center.

Based on his experiment Rutheford concluded that atoms were?
The conclusion was that an atom contain a positive nucleus.

What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
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.
Which of the following provided evidence that most of the mass of the atom as well as all of the positive charge is concentrated in a very small core the nucleus?
The gold foil experiment conducted by Ernest Rutherford provided evidence that most of the mass of the atom, as well as all of the positive charge, is concentrated in a very small core called the nucleus. In this experiment, alpha particles were scattered by the positively charged nucleus of gold atoms, leading to the conclusion that atoms have a dense, positively charged nucleus at their center.
Who provided evidence for the exsitist of an atomic nucleus?
This is the well known gold foil experiment: alpha particles are scattered by the atomic nucleus.
What did ernest rutherfords gold foil experiment demonstrate about atoms?
The conclusion was that an atom has a nucleus (center) with a positive charge.
Which observations helped Rutherford determine that atoms have tiny dense positively charged nuclei?
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.
What part of the atoms caused the particles to bounce?
The heavy, dense nucleus of the atom caused the alpha particles to bounce back in Rutherford's experiment.
Who said Protons exist?
Ernest Rutherford is credited with discovering that protons exist. In his famous gold foil experiment, Rutherford observed that alpha particles were deflected by the positive charge of the nucleus, leading to the conclusion that the nucleus contains positively charged particles which we now know as protons.
