They found that the rays bent towards positively charged plates and away from negatively charged plates. Knowing that objects which have like charges repel eachother, they concluded that the rays have a negative charge.

How did JJ Thompson demonstrate the existence of the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
What scientist designed an experiment that enabled the first successful detection of an individual subatomic particle?
J.J. Thomson (Sir Joseph John Thomson, 1856-1940), who demonstrated in 1897 that "cathode rays" consisted of negatively-charged particles, later named electrons.
What did JJ Thompson's Cathode ray experiment suggest?
His cathode ray experiment suggested that atoms are not indivisible and that they contain negatively charged particles called electrons, embedded in a positively charged substance within the atom. It was called the plum pudding model.
How are cathode charged?
negatively charged
A cathode ray is deflected away from a negatively charged object What property of the cathode ray is shown by these phenomena?
The property shown by the phenomena is that the cathode ray is negatively charged. A cathode ray is also called an electron beam or an a-beam.
What particle was observed in the cathode rays?
The negatively charged particle called electron.
What sub atomic particle is a cathode ray?
Electrons--the cathode is negatively charged, the anode is positively charged.
Who performed an experiment with cathode ray tubes?
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
What are the role of cathode tubes in atom?
cathode tubes were used to detect the particle in an atom & found that negatively charged particles(electrons) are there in an atom.
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.
Which scientist did experiments involing a form of cathode ray tube?
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
How did JJ Thompson demonstrate the existence of the electron?

This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
Describe experimental basis for existence of electrons in an atom?
J.J. Thompson proved the electron's existence through the cathode ray experiment.
What did J J. Thomsons experiment show?
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
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
What did JJ Thomson's cathode-ray tube experiment show?
Thompson observed that these rays are negatively electrically charged.
How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
