What are the rays in the cathode ray tubepositive or negative or neutral?

The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.

Cathode rays all have same negative charge?
True
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.
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
Cathode rays were shown to be a stream of?
Cathode rays are electrons.
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
How do scientists detect cathode rays?
Cathode rays are found in vacuum tubes. Scientists are able to view them when they are a negative cathode because they emit a light and can glow.
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.
Cathode rays all have same negative charge?
True
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.
Why do cathode rays move from the negative end of the tube to the positive end?
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
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
Why are cathode rays deflected away from a negatively charged plate?
Alpha Rays are attracted to a negatively charged plate because they consist of positively charged particles.
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.
Do the rays produced in cathode tube deflect towards negative plate?
The electron beam produced in the cathode is essentially negative (with respect to the anode), therefore it tends to go towards potentials above the cathode's potential (more positive or less negative, as you wish).
Cathode rays were found to be made of protons.?
Cathode rays are electrons.
