In a famous experiment Rutherford bombarded a very thin gold (Au) foil with positively charged alpha particles. They found that most of the alpha particles passed right through the Au foil. However a?

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.
When positively charged particles bounced back from the foil Rutherford called this?
Deflection of alpha particles
How is Thomson's model based on the experiment of passing alpha particles through the gold foil?
The results of this experiment led to the model of the atom called "Rutherford's model", rather than Thomson's model, which it basically disproved. Some of the alpha particles were deflected in ways that suggested to Rutherford that most of the atom's mass was concentrated in a positively charged "nucleus".
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.
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.
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
Which scientists proposed the nuclear a tomic model with a centrally located positively charged nucleus based on the result of his gold foil experiment?
Ernest Rutherford published a paper proposing the planetary model in 1911. This followed the experiment performed by Hans Geiger and Ernest Marsden under the direction of Rutherford in 1909, where gold foil was bombarded with alpha particles .
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.
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.
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.
What was the term Rutherford gave positively charged particles?
protons
What Rutherford might have observed if he had bombarded copper metal instead of gold with alpha particles?
have a guess
Why does rutherford's gold-foil experiment conclude that the atom is mostly empty space with a small massive positively charged center?
because few particles bounced back
