Why did the path of only some alpha particles deviate in Rutherford experiment?

Alpha particles are positively charged helium nuclei. As such, they are repelled by other positively-charged nuclei. In Rutherford's experiment, he used gold foil. Since gold atoms have large, massive nuclei, the alpha particles were easily repelled by the large gold atom nuclei, and they were scattered in different directions.

Why the alpha particles could not smash the nucleus apart?
The alpha particle is positively charged (as is the nucleus) and is heavy compared with the neutron that is neutral and lighter than the alpha particle.Another viewpoint:It depends what experiment the question is about. For example, over a hundred years ago, Rutherford bombarded gold foil with alpha particles and some "bounced off" what we now call the nucleus of the atoms. However, about ten years later he did experiments in which alpha particles did indeed "split" atomic nuclei. So, sometimes alpha particles can certainly smash a nucleus apart.
How neutrons were discovered?
When Beryllium is bombarded with alpha particle some stream of particles are found to be coming out. First such an experiment was done by Bothe and Becker. But they mistook those particles coming out as intense gamma radiation as it was not deflected by magnetic or electric field. Later the same experiment was done by Fredrick Joliot and his wife Irene Joliot. They too lost the chance of finding that as neutron. Finally James Chadwick did the same experiment and found precisely the particles having almost equal mass as that of proton and not having any charge. He named that one as Neutron.
Which particle is most massive in radioactivity?
You think probable to alpha particles.
What is meant by bombarding a thin sheet of beryllium by alpha particles?
"Bombarding a thin sheet of beryllium by alpha particles" generates a neutron flux. In nuclear weapons design, it is sometimes necessary to produce a heavy flux of neutrons at just the right instant in time, relative to the assembly of super prompt critical mass. It turns out that beryllium is a good producer of neutrons when bombarded with alpha. The alpha source is often polonium. One design has the two in sheets that do not interact with each other, due to separation with gold and nickel, until the initiating shock wave compresses them together, along with the mass of fissile material, usually plutonium.
An alpha particle is composed of which subatomic particles?
A Helium Nucleus so 2 protons and 2 neutrons Quarks are contained within the neutrons & protons and there are many types
Do the alpha particles in Rutherford's experiment contain electrons?
Alpha particles are helium-4 nuclei; they do not contain electrons.
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
The alpha particles beam is scattered.
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
Why did Rutherford conclude that an atoms nucleus has a posotive charge instead of a negative charge?
when carrying out the alpha scattering experiment, he observed that some alpha particles got deflected from their course. as alpha particles are helium nuclei, they are positively charged. the fact that they deviate made him think that there might be some repulsion between the particles and the nucleus. as positive charges repel each other, he determined the nucleus to be positively charged.
Are the atoms in the gold foil experiment a positive or negative charge?
Positively charged atoms, In Rutherford's experiment he bombarded an extremely thin piece of gold foil with alpha particles. Alpha particles are tiny, high energy, positively charged particles.
Why did Rutherford use alpha particles rather than electrons for his scattering experenment?
Because the alpha particles are positively charged. In order for the experiment to work, the positive alpha particles must be attracted to the negatively charged gold foil.
Who conducted the gold foil experiment to discover the nucleaus?
Ernest Rutherford was responsible for the Gold Foil experiment. A great portion of Ernest Rutherford's research included the study of alpha particles.
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 did sir ernest Rutherford work with?
If you're talking about the experiment with the alpha particles, then it was Hans Gieger and Ernest Marsden.

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.
In Rutherford's gold experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil?
positive
