When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
In Rutherford's metal foil experiment, some alpha particles passed straight through the foil, while others were deflected at various angles. A small fraction of the alpha particles even bounced back towards the source. This led Rutherford to conclude that atoms have a small, dense nucleus at their center.
Which scientist was the first to conclude through experimentation that atoms have positive charges in their nuclei?
Hans Geiger and Ernest Marsden. Rutherford was the supervisor and explained the unexpected results, so his name is usually attached to the experiment as well, but it was Geiger and Marsden who actually did it.
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.
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
How did the results of Rutherfords gold foil experiment differ from his expectations?
Everyone thought that the alpha particles would go through the gold- foil with little deflection. When the alpha particle passed straight through the gold atoms with no deflection or bounced straight back a small fraction bounced off at a large angle, or bounced straight back to the source. Rutherford came up with a new theory of the atom, that the atom is mostly empty space and in the center there is a nucleus. this is known as the nucleus atom.

What did Rutherford observe when he fired alpha partices at pieces of thin metal foil?
Rutherford observed that most alpha particles passed straight through the foil, but a small percentage were deflected at large angles. This led him to conclude that the atom has a small, dense nucleus surrounded by mostly empty space.
What is the observation and reason of Rutherford gold foil experiments?
Observation: Most of the alpha particles passed straight through the gold foil, but a small fraction were deflected at large angles. Reason: This led Rutherford to conclude that atoms are mostly empty space with a dense positively charged nucleus at the center, which caused the deflection of the positively charged alpha particles.
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.
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.
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.
Particles fired at gold foil some going straight through?
The observation that some particles fired at gold foil went straight through indicated that the majority of the atom is empty space. This led to the discovery of the nucleus by Ernest Rutherford, who proposed the nuclear model of the atom.
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 )
Which scientist was the first to conclude through experimentation that atoms have positive charges in their nuclei?
Hans Geiger and Ernest Marsden. Rutherford was the supervisor and explained the unexpected results, so his name is usually attached to the experiment as well, but it was Geiger and Marsden who actually did it.
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.
The kind of particle Rutherford used to shoot through gold foil?
Rutherford shot high-energy alpha particles (two protons and two neutrons, or a helium nucleus) at the gold foil. A small fraction of these alpha particles bounced back, and that is how Rutherford discovered the nucleus.
