What piece of equipment did JJ Thomson use in his atomic theory experiment?

JJ Thomson used a cathode ray tube in his atomic theory experiment, known as the cathode ray experiment. By observing the behavior of cathode rays in the tube, he was able to discover the existence of electrons and propose the plum pudding model of the atom.


What equipment qould be needed to perform this experiment?

To perform this experiment, you would need a spectrophotometer to measure the absorbance of the light passing through the solution, cuvettes to hold the solutions being tested, a light source to shine light through the solution, and the necessary chemicals and reagents for the specific experiment being conducted.


What did JJ Thomson's cathode-ray tube experiment show?

Thompson observed that these rays are negatively electrically charged.


Why did jj Thomson do his experiment?

J.J. Thomson performed his experiment to discover the existence of subatomic particles known as electrons. By studying the properties of cathode rays, he was able to determine the charge-to-mass ratio of electrons and propose the plum pudding model of the atom.


What describes the material and equipment needed and procedures to follow in an experiment?

The materials and equipment list includes all items needed for the experiment, such as beakers, thermometers, and chemicals. The procedures outline the step-by-step instructions to conduct the experiment, including mixing instructions, measurement techniques, and safety precautions. It is important to follow these guidelines accurately to ensure reliable results and maintain safety in the lab.
