Is it true some particles bounce off the gold foil because they hit protons in the nucleus in the Rutherford gold foil experiment?

Yes, this is true because the positive core of the atom was denser than the alpha particles hitting the gold foil, this allowed Rutherford to create a more correct version of the atomic diagram.
Alpha particles (Helium nuclei) are two protons and two neutrons (stuck together). They pass through much of the space that an atom of gold takes up, because most of the space is merely space (surrounded by electrons). When an alpha particle hits (or comes close) to the nucleus of gold, it get deflected (or bounces). The gold nucleus contains protons and neutrons.

Yes, that is true. In the Rutherford gold foil experiment, some alpha particles were observed to bounce off the gold foil because they came close to or hit the positive protons present in the nucleus of gold atoms. This result led to the discovery of the atomic nucleus and the understanding that atoms are mostly empty space.

What did the particles in Rutherford' s experiment do?
Rutherford was expecting the result to be what JJ Thomson had predicted. That the Alpha Particles just pass through the gold foil, not rebound, like the result. JJ Thomson thought of this result because of his plum pudding model.
Who is series of experiments identified the nucleus of an atom?
The gold-foil experiment
Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
ernest Rutherford
What is significant about Ernest Rutherford?
Rutherford came up with the basic structure of an atom using his gold foil experiment. He shot alpha particles(hydrogen nuclei) at a peice of gold foil and watched the results. He found from this experiment that the atom contains a dense, positively charged nucleus, negative particles in "electron clouds" and is made up of mostly empty space.
What did Rutherford gold foil experiment suggest about the structure of an atom?
1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil) 2) Atoms had a dense nucleus (because few alpha particles bounced straight back from the atoms) 3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
Rutherford used the gold foil experiment to figure out that an atom had charged particles in the nucleus
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.
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?
Who discovered the nucleus using his gold foil experiment?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
What is the name of the scientists who first proposed that atoms have a nucleus?
Ernest Rutherford, following the "gold foil" experiment.
What did Rutherford discover about atom structure?
Rutherford oversaw the gold foil experiment. This experiment showed that the atom is mostly empty space and that most of its mass is concentrated in a tiny central core called the atomic nucleus.
How did Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
What did the particles in Rutherford' s experiment do?

The term Rutherford gave to the positively charged particles in the nucleus of an atom?
In 1920, Rutherford gave the name proton to the positively charged particles in the nucleus of an atom.
How is the Rutherford Experiment Done?
To do the Rutherford Experiment, you have to shoot alpha particles at gold foil to and see where the particles pass through and where they do not. This will give you a general idea of what Rutherford did to discover the nucleus of an atom. However, alpha particles are very hard to come upon, as they are the nucleus of Carbon. Rutherford knew that alpha particles are about 7000 times more massive than electrons and are positively charged and the charge is twice the magnitude of the charge of electrons.when Rutherford directed a beam of alpha particles at a thin gold foil,he found that almost all particles passed through it without deflecting.A very small were deflected at an angle, however, and a few actually bounded back toward the particle source.
Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
