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.
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 is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
Who discovered negative charge?
J.J Thompson in 1897 demonstrated that cathode rays are composed of tiny, negatively charged subatomic particles called electrons.
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 did JJ Thompson know the charge of the particles?
from his cathode ray tube experiment
Why did j.j reason the electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
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.
Who discovered subatomic particles with no charge?
The neutron was discovered in 1932 by James Chadwick.
How did the cathode's tube experiment lead to the conclusion that atoms contain electrons?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
Is goldstien discovered proton?
Off course. He discovered the proton with the help of discharge tube with a perforated Cathode. Some positively charge particles were detected behind perforated cathode. these particles were of different mass and charge for different gases used in the tube (i.e. had different m/e). the lightest particles were formed when hydrogen gas was used. So the word proton was give so, because these particles for hydrogen were the lightest and came on first in order of mass. (Greek 'Protos'= First)
How did William crooks know that the glow in the cathode-ray tube resulted from stream of charge particles?
it was deflected by a magnet
