What did Thomson's cathode-ray tube experiments help scientists learn?
Thomson's cathode-ray tube experiments helped scientists learn about electrodes and that atoms were comprised of many small particles, which they did not know existed. They also learned from this tube that all the electrons were the same regardless of what elements they came from.
What do scientist use tools to do?
Make stuff for experiments, do experiments and analyse the results of experiments.
Why is a experiment designed?
Scientist design experiments to test something.
How do scientists learn something new from controlled experiments?
they use controlled experiments to help them find out if it works or not.
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
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.
What did Thomsons experiments prove?
J. Thomson discovered the electron.
What did JJ Thomson work with?
Discovery of electron was done by JJ Thomson. he and others studied the properties of cathode rays by conducting experiments.
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.
What was the name of the concept model that Thomson proposed based on his experiments?
JJ Thomson called his model of the atom the plum pudding model.
Which scientist did experiments involving a form of cathode ray tube?
It was the investigator J. J. Thomson who did experiments with an early cathode ray tube. You'll find a link below.
When did JJ Thomson do stuff about the atom?
Thomson did much of his most important work in the late 1800's. His famous cathode ray experiments where conducted in 1897.
Who discovered conducted experiments in combining elements?
John Dalton conducted experiments combining elements with atoms.
Who proposed the existence of electron?
‎J. J. Thomson discovered the electron in experiments done in 1897.
How did Thomson's experiment change daltons atomic model?
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.
