Rutherford was expecting slight to moderate deflections because the idea was that the positive charge in an atom was distributed throughout the atom. But when he found large deflections he had to conclude, correctly, that the positive charge had to be concentrated into a tiny volume, in order to provide the huge electric fields needed to cause this. We now call this point the nucleus and it is indeed the cause of the observation.

Why is Rutherford's experiment called the gold foil experiment?
Rutherford's experiment is called the gold foil experiment because a thin sheet of gold foil was used as the target in the experiment. This gold foil was bombarded with alpha particles to study the scattering of the particles and led to the discovery of the atomic nucleus.
What will happen if you use beta particles on gold foil?
If beta particles are used on gold foil, they may interact with the gold atoms causing ionization and scattering of the beta particles. This interaction can lead to changes in the properties of the gold foil, such as altering its conductivity or creating defects in the crystal lattice.
Does each substance has particles?
tiny particles
Tiny particles which makes matter?
These particles are called atoms.
In rutherfords gold foil experiment he concluded that the atom is mostly empty space with a small massive positively chargeed centrer because?
most of the alpha particles passed through the gold foil undeflected or with slight deflection, suggesting that the atom is mostly made up of empty space. The few alpha particles that were deflected back indicated the presence of a small, dense, positively charged nucleus at the center of the atom.
What happened to the alpha particles as they hit the gold foil?
They stop.
What was ernest rutherfords's experiment?
he shot tiny alpha particles throug a piece of gold foil.
Which observations helped Rutherford determine that atoms have tiny dense positively charged nuclei?
Rutherford's gold foil experiment showed that most alpha particles passed through the foil, but some were deflected at large angles, indicating a concentrated positive charge in a small region. Additionally, the discovery of the atomic nucleus was supported by the scattering of alpha particles, which led to the conclusion that atoms have a small, dense, positively charged nucleus at their center.

Are the atoms in the gold foil experiment a positive or negative charge?
The atoms in the gold foil experiment are positively charged. This experiment was conducted by Ernest Rutherford in which he discovered that the positive charge of an atom is concentrated in the nucleus, and most of the atom is empty space with electrons orbiting around it.

Why is Rutherford' experiment called the gold foil experiment?
In the experiment, Rutherford found the nucleus using gold foil.because he used a thin sheet of gold foil.Because he used a gold foil (the only metal that can be hammered into a 1 atom thick foil without tearing) in an attempt to scatter alpha particles.The unexpected result that instead of all of the alpha particles scattering through small forward angles, a few bounced almost directly back to the source. This made the Thompson "plum pudding" model of the atom unworkable and suggested that each atom had a tiny "infinitely hard" kernel somewhere inside it. Rutherford named this kernel the nucleus.

What is the experimental evidence that most of an atomis empty space?
Ernest Rutherford determined that with his famous gold foil experiment. Here's what he did: he rigged an alpha particle emitter to shoot alpha particles (made up of 2 protons and 2 neutrons) through a thin piece of gold foil to hit a background where the particles would register their position when they hit. Most of the alpha particles passed clean through the gold foil without touching anything. But a certain small percentage bounced back, and a certain small percentage were deflected. Here's what he determined: 1. atoms are mostly empty space, because most passed clean through. 2. atoms have a nucleus which is tiny, but dense compared with the electron cloud. 3. that nucleus is positively charged, because it deflected the positively charged alpha particles. This experiment radically changed our view of the structure of an atom, and is one of the most famous experiments ever conducted in science.
Are particles large?
Not at all! Particles are tiny little things
