Rutherford used his gold foil experiment as evidence for a new atomic model. He suggested that the atom contained a small positively charged nulceus surrounded by a large void filled with only a few electrons orbiting the nucleus.
What other experiment or evidence assisted in the creation of this model
If your here from usa test prep its d the one that starts with thomson
Well I suppose Thomson's model was a help in that Rutherford used the scattering experiment to show that the atom was not plum pudding but a dime in a lake nucleus way inside an electron cloud.
One of the major experiments that assisted in the creation of Rutherford's atomic model was the Thomson cathode ray tube experiment. In this experiment, J.J. Thomson discovered the existence of electrons by observing the deflection of cathode rays (electrically charged particles) in a cathode ray tube.
To conduct the Thomson cathode ray tube experiment and observe the deflection of cathode rays, you would need the following materials and setup:
1. Cathode ray tube: This is a sealed glass tube containing a cathode (negatively charged electrode) and an anode (positively charged electrode) at either end. The tube is filled with a low-pressure gas.
2. High voltage power supply: This is used to create a potential difference between the cathode and the anode.
3. Magnetic field source: You will need a source of a magnetic field to observe the deflection of the cathode rays.
To conduct the experiment and observe the deflection of cathode rays, follow these steps:
1. Set up the cathode ray tube experiment by connecting the high voltage power supply to the cathode and anode of the tube, ensuring the tube is sealed and airtight.
2. Apply a high voltage to the tube, creating an electric field between the cathode and the anode. This causes the gas within the tube to ionize and form cathode rays.
3. Place a magnetic field source near the cathode ray tube. The magnetic field will exert a force on the moving charged particles (electrons) in the cathode rays.
4. Observe the deflection of the cathode rays. If the rays deflect towards the positive plate, it indicates that the cathode rays are negatively charged particles (electrons).
Based on the results of the Thomson cathode ray tube experiment, it was concluded that atoms must contain negatively charged particles (electrons), as the deflection of the cathode rays showed the presence of these subatomic particles. This experiment provided evidence against the previously proposed "plum pudding" model of the atom, where positive charge was evenly distributed throughout a mass of negative charge.
Rutherford built upon Thomson's discovery of electrons and their deflection to design his gold foil experiment. In this experiment, alpha particles (positively charged particles) were directed at a thin gold foil, and the observations made during the experiment led to the conclusion that atoms have a small, dense, positively charged nucleus at the center, with electrons orbiting the nucleus in empty space. This became known as the Rutherford nuclear model of the atom.
