William Crookes concluded from cathode rays that there was something more to an atom. Something that carried an electrical current. This was a mystery at the time. William Crooke's experiment helped pave the way for J.J. Thompson's discovery of the electron.

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 is the formation of anode and cathode rays?
Goldstein used a gas discharge tube which had a perforated cathode. When a high electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays," which are streams of electronswhich move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode
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.
Why is the cathode-ray tube in figure 4 connected to a vacuum pump?
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.
Where did the electrons from cathode ray come from?
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
What did William Crookes study?
William Crookes is known for the study of cathode rays.
When did William Crookes discover cathode rays?
1895
How did William Crookes determine the nature of the beam in cathode ray tube?
In his investigations of the conduction of electricity in low pressure gases, William Crookes discovered that as the pressure was lowered, the negative electrode (cathode) appeared to emit rays (the so-called cathode rays, now known to be a stream of free electrons, and used in cathode ray display devices).
What did scientists conclude from observing that within a cathode tube cathode rays could move a paddle wheel placed in their paths?
bullcrap
Is William crooks is the inventor of cathode rays?
Yes! He is!
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.
Which scientist did experiments involing a form of cathode ray tube?
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
What did Thomson conclude about the particles in cathode rays?
they are deflected toward positive terminal in an electric field
Cathode rays were found to be made of protons.?
Cathode rays are electrons.
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.
