In thomson's experiment why was the glowing beam repelled by a negatively charged plate?
The experiment showed the relation of positive/negative charges. The beam was made of positively charged ions, which were repelled. -there is another answer to this question that says " because it was attracted to the positive charged plate" this is FALSE, this is just a person trying to make a smart remark. --------- Cathode rays are a beam of electrons; electrons are elementary particles with a negative electrical charge.
What is the evidence that show cathode rays consists of charged particles?
in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.
What evidence did Thompson have that his glowing beam contained negative particles?
The beam was repelled by the negative charged plate and attracted by the positively charged plate
When placed between oppositely charged metal plates the region of a water molecule attracted to the negative plate is what?
partially positively charged hydrogen end of the molecule.
Give a reason why it is unlikely that an F- ion would reach the detector in a mass spectrometer?
It's because the F- is a negatively charged ion, therefore it would not be attracted to the negative plate so it's not accelerated and thus it would not reach the detector.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes. Cathode rays, otherwise known as electrons, are repelled by a negative charge, and attracted to a positive charge.
What effect will a positively charged metal plate have on a cathode ray?
Since a cathode ray is a stream of electrons, and since electrons are negatively charged, a positively charged metal plate would cause a deflection in the cathode ray towards the plate.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
When Thomson held a positively charged plate near the cathode ray the beam bent toward the plate What conclusion can be drawn from this observation?
The cathode "ray' must have been made up of negatively charged particles, now called electrons.

How did Thomson know that the electrons that he had discovered had a negative charge?
He devised a crook's tube with a near perfect vaccum with two aluminum plates in the center of the tube. One plate served as the anode to a circuit while the other served as a cathode, effectively creating a magnetic field between then with a negative field on one side and a positve field on the other. electrons (cathode rays) were then passed through, Because electrons are negatively charged, the negatively charged anode will repel them and force them to strike the florescent screen at a lower spot than if allowed to pass through freely. When the current it reversed the electrons strike the screen at a higher point than would normally occur
What happens when positively charged plate connects with negatively charged plate?
They neutralize.
How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
What is the evidence that show cathode rays consists of charged particles?
in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.
When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.
Are protons attracted to a negatively charged metallic plate?
yes they are.
