What did Thomson use in his experiments?
J.J. Thomson studied the deflection of cathode rays in electric and magnetic fields.
What was Thompson working with when he discovered the cathode rays?
Thomson discovered cathode rays when he was working with electrons. He was performing experiments with the electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
How did the results of JJ Thomson's experiments change how scientists thought about atoms?
He described the atom as a sea of positive charge sprinkled with electrons
What did JJ Thomson's experiment show?
A. the atom is like a uniform sphere.b. Cathode rays are made up of electrons.c. All atoms undergo radioacitve decay.d. Isotopes undergo radioactive decay.The answer is A!The atom is like a uniform spere!
What did eugen goldstein contribute in the history of atom?
He is sometimes called the discoverer of protons. He did experiments with cathode ray tubes, which knock electrons off atoms and attract them to a positively-charged electrode (the cathode). He noticed that a second stream of particles was attracted to the negatively-charged electrode (the anode), so he called them anode rays. However, it was left to one of his students to discover that these rays were sometimes pure protons. His experiments gave him a picture of atomic structure that was decades ahead of its time, and similar to what we know today. However, he did not follow up on his work, and was largely ignored by his peers.
Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
Why did Thomson see cathode rays with every element?
Thomson observed cathode rays with every element because cathode rays are composed of electrons, which are fundamental particles present in all atoms regardless of the element. When a high voltage is applied in a vacuum tube, electrons are emitted from the cathode and accelerate toward the anode, creating cathode rays. This universal presence of electrons in all elements allowed Thomson to consistently detect cathode rays across different materials. His experiments demonstrated that these rays were not dependent on the type of gas or metal used in the cathode.
What experimrents did jj Thomson?
After experiments with cathode rays Thomson discovered that these rays are deflected in an electrical field; and from this he proposed the existence of electrons.
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
What would happen to the deflection of the cathode ray if the particle in the rays were heavier?
deflect more
What was John Thomson's experiment for the modern model?
John Thomson's experiment involved studying the properties of cathode rays in a cathode ray tube. By observing the behavior of these rays in the presence of electric and magnetic fields, Thomson was able to determine the charge-to-mass ratio of the electron. This experiment provided important evidence for the existence of subatomic particles and laid the groundwork for the development of the modern atomic model.
What did j.j Thomson experiment with?
J.J. Thomson experimented with cathode rays in a vacuum tube, which led to the discovery of the electron in 1897. By measuring the charge-to-mass ratio of electrons, he determined that they were a fundamental particle and were present in all atoms.
What did Thomson conclude about the particles in cathode?
The immaterial nature and the aetherial hypothesis of cathode rays were proved wrong by J. J. Thomson. He concluded that the rays were comprised of particles. His entire works can be divided into three different experiments. In the first, the magnetic effect on cathode rays was studied while in the second, the rays were deflected by an electric field.
What did Thomson use in his experiments?
J.J. Thomson studied the deflection of cathode rays in electric and magnetic fields.
In the absence of magnetic fields cathode rays do what?
In the absence of magnetic fields, cathode rays will continue to travel in a straight line. Magnetic fields can be used to deflect or focus cathode rays, but without these fields, the electrons will not be influenced and will travel unaffected.
Thomson made his discovery about the atom during an experiment using?
Cathode Rays
What did J. J. Thomson experiment with?
J. J. Thomson experimented with cathode rays and discovered the electron, leading to the development of the plum pudding model of the atom.
