In Rutherford's gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
In Rutherford's gold experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil?
Yes, in Rutherford's gold foil experiment, he observed that some alpha particles were deflected at very large angles and even bounced straight back, indicating that they were hitting something small and dense (the atomic nucleus) within the gold foil. This observation led to the development of the nuclear model of the atom.
What was the conclusion of Rutherford's gold foil experiment in terms of an atom's mass and volume?
Rutherford found that when when he aimed alpha particles at a thin sheet of gold foil, that some of the particles were deflecteted and didn't go straight through the foil. The reason for this turned out the be that they ran into the nucleus. Most of the particles did go straight through, so Rutherford concluded that the atom was mostly empty space. He also concluded that the center of the atom contained the nucleus and had positively charged particles he called protons.
Which particle was discovered during the gold foil experiment?
The discovery of the atomic nucleus was made during the gold foil experiment by Ernest Rutherford in 1909. He observed that most of the alpha particles passed straight through the gold foil, indicating that atoms have a small, dense nucleus at their center.
Briefly describe Rutherford's experiment?
The Gold Foil Expirament-Rutherford A line of photons were shot through a thin piece of gold, and rutharford theorized that they should pass through. However some passed through while others deflected and some reflected backwards. It gave proof that atoms have a nucleus
Would particles pass straight through gold foil?
No, most particles would not pass straight through gold foil. Gold is a dense material that effectively blocks or deflects particles like alpha particles due to its high atomic number and density. This property is the basis for Ernest Rutherford's gold foil experiment which led to the discovery of the atomic nucleus.

How did Rutherford know an atom was mostly empty pace?
Rutherford discovered that atoms are mostly empty space through his famous gold foil experiment. He observed that most of the alpha particles passed straight through the foil, indicating that atoms had a lot of empty space. The few particles that were deflected showed that the positive charge in an atom is concentrated in a small nucleus at the center.
What are the main ideas of e Rutherford gold foil experiment?
basically, Rutherford shot postively charged particles at a thin sheet of gold foil. most of the particles passed straight through, but some bounced off at sharp angles. This implies that most of the atom is empy space (which is why most of the particles go straight throught) , but there is a positively charged nucleus at the center (which repels the postively charged particles, so if a particle hits the nucleus, it bounces off )
What is Rutherford's experiment with gold foil and alpha particles?
The initial discovery of "Rutherford Scattering" was made by Hans Geiger and Ernest Marsden in 1909 when they performed the gold foil experiment under the direction of Rutherford, in which they fired a beam of alpha particles (helium nuclei) at layers of gold leaf only a few atoms thick. The intriguing results showed that around 1 in 8000 alpha particles were deflected by very large angles (over 90°), while the rest passed straight through with little or no deflection. From this, Rutherford concluded that the majority of the mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons. When a (positive) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles. The small size of the nucleus explained the small number of alpha particles that were repelled in this way.

What did Rutherford say about the small number of particles that bounced straight back?
Rutherford fired alpha particles at a sheet of atoms in order to determine the atomic structure. The alpha particle is positively charged. Those particles that bounce straight back are the ones that hit the nucleus of the atom and were repelled by the nucleus's positive charge.

Do atoms have empty space?
Yes. In 1908, Rutherford conducted an experiment of shooting a beam of alpha particles through a sheet of tinfoil. Most of the alpha particles went straight through the foil, which proves that there are empty spaces in atoms. And the rest of the particles that didn't go straight through the foil are deflected at acute angles, those particles are deflected by the positive nucleus in the center of the atoms.
What did Rutherford observed that surprise him?
Most of the alpha particles shot at the gold foil went straight through the foil.
Why does rutherford's gold-foil experiment conclude that the atom is mostly empty space with a small massive positively charged center?
In Rutherford's gold-foil experiment, when alpha particles were shot at gold foil, most passed straight through, but some were deflected at large angles. This led Rutherford to conclude that the atom is mostly empty space, with a small, dense, positively charged nucleus at the center that caused the deflections. The majority of the atom's volume is made up of this empty space, with the nucleus containing most of the atom's mass.
