What was the experimental evidence that Thomson had discovered the existence of a subatomic particle when working with cathode rays?

Thomson discovered the electron and proved that it existed without ever being able to see or isolate one. Electrons were the first subatomic particles to be discovered, the first particle of matter identified that was smaller than an atom. This discovery also finally provided some physical proof of, and description of, the basic unit that carried electricity. Thomson attached thin metal plates inside his cathode ray tube to a battery and showed that an electrical field could also deflect cathode rays.

The line spectra of atoms provides experimental evidence for?
the arrangment of electrons
What experimental evidence do you have for the existence of ionic bonding?
That the disassociated ions conduct electricity. They must be charged and oppositely charged to conduct electricity in solution and the must dissasociate to a reasonable degree to do so. Thus. NaCl Na + ( cation ) and Cl - (anion ) are electrolytes conducting electricity in solution. This is a common chemistry class demonstration.
What experimental evidence led to the formulation of the law of multiple proportions?
that he researched atoms and thought of how to become famous by making a theory
What ideas about the atom changed when new evidence is discovered?
Atoms cannot be divided
What experimental evidence led to bohr to believe that electrons can posses only specific amounts of energy?
The line spectra produced by excited atoms
Which particle did j.j. Thomson discover?
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
Is atom discovered or imagined?
The existence of atoms was hypothesised, imagined if you like. Their existence is supported by a huge volume of experimental and theoretical evidence, but there is no absolute proof, and probably never will be. Democritus, more than 2000 years ago imagined the existence of atoms.
What is the evidence for the existence of dark matter in the universe?
The evidence for the existence of dark matter in the universe includes the extra mass of Galactic clusters discovered by Fritz Zwicky, and the spinning galaxies which rotate at the same speed as discovered by Vera Rubin.
What is experimental evidence?
Experimental evidence is data obtained through conducting an experiment. For example, if I measure the boiling point of a substance at 500 degrees Fahrenheit by boiling the substance, 500 degrees is my experimental evidence.
Are coincidences evidence of God's existence?
Not likely. Coincidences are evidence of coincidence, or if you will, random chaos, which is what the universe is all about. Asking if they are evidence of God's existence is like asking if water is evidence of a fish's existence.
Who did not have experimental evidence to support his of the atom?
Democritus
What is a statement that does not have experimental evidence to support it?
Hypothesis.
What is evidence for the existence of God?
Nothing. There is no evidence as God does not exist. Thank you and good night. FALSE ANSWER ^^^^ There is an evidence for the existence of God. Nature can be used as an evidence for the existence of God, and some natural events that technology or man cannot make.
Is there any evidence of the Holy Ghost?
Just as there is no evidence for the existence of God, so there is no evidence for the existence of the Holy Ghost. It is a matter of faith, and faith alone.
Who did not have experimental evidence to support his theory of the atom?
democritus
Are theories in science based of experimental evidence?
Yes.
. J. J. Thomson and experiments provided evidence that an atom .?
a cathode ray
