Rutherford's alpha particle experiment demonstrated that Thomson's plum pudding model of the atom was incorrect. By directing alpha particles at a thin gold foil, Rutherford observed that some particles were deflected at large angles, indicating the presence of a dense, positively charged nucleus at the center of the atom. This unexpected result suggested that atoms have a small, concentrated core rather than being a diffuse cloud of positive charge, leading to the development of the nuclear model of the atom.
What else can I help you with?
When was rutherfords model created?
Rutherfords Model is Rutherfords Model... thats it, its just a model.. go look it up on google images im sure you will figure it out by then.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
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".
What were Lord Ernest Rutherfords Accomplishments?
he found faults in the atomic theory of jj Thompson
What technology was available to Thomson that enabled him to make his discovery on atoms?
For what might be his most famous experiment, the refutation of Thomson's 'plum pudding' model, only limited apparatus was used: a source of positively charged alpha particles that would be deflected by atomic nuclei, some thin gold foil, a collimitor to narrow the beam of alpha particles, a zinc sulphide screen to register any alpha particles deflected by nuclei, and a microscope to render flashes on this screen visible to the naked eye. All in a darkened room. The various parts of the apparatus could be moved in an arc relative to one another to verify whether scattering of the alpha particles had occurred. Rutherford didn't like statistics but the results were unequivocal. Please see the link.
How did Rutherford's alpha scattering experiment show that Thomson's plum pudding model of the atom incorrect?
Rutherfords experiment proved the existence of a nucleus as some alpha particles "bounced back" from the gold foil sample . Thomson model did not involve a nucleus and predicted just a slight deflection or none at all.
What scientific inquiry skill was Rutherford using in selecting Thomson's model for investigation?
Rutherford was using the scientific inquiry skill of hypothesis testing when selecting Thomson's model for investigation. He proposed an alternative model to test and refine the existing understanding of the structure of the atom, setting up experiments to gather evidence that would support or refute Thomson's model.
What was ernest rutherfords's experiment?
he shot tiny alpha particles throug a piece of gold foil.
When was rutherfords model created?
Rutherfords Model is Rutherfords Model... thats it, its just a model.. go look it up on google images im sure you will figure it out by then.
Rutherfords alpha scattering experiments showed that the charge on the nucleus of the atom must be?
The atomic nucleus is positive because contain protons.
Rutherfords alpha scattering experiment showed that the charge on the nucleus of the atom must be?
Rutherford's alpha scattering experiment showed that the charge on the nucleus of the atom must be positive because the alpha particles were deflected by the concentrated positive charge in the nucleus.
How does the design of Rutherfords experiment show what he was trying to find?
The presence of a tine nucleus
Howes the design of rutherfords experiment show what he was trying to find out?
The presence of a tine nucleus
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
Did Ernest Rutherfords results fit with J.J Thomsons view of the atom?
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
How was Thomsons atomic theory different from Rutherfords atomic theory?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
What caused the deflection of the alpha particles in Rutherfords gold foil experiment?
A zinc sulfide coated screen surrounding the gold foil produced a flash of light whenever it was struck by an alpha particle. By noting where the flash occurred, the scientists could determine if the atoms in the gold foil deflected the alpha particles.
