Body Quote by Joseph John Thomson
“As the cathode rays carry a charge of negative electricity, are deflected by an electrostatic force as if they were negatively electrified, and are acted on by a magnetic force in just the way in which this force would act on a negatively electrified body moving along the path of these rays, I can see no escape from the conclusion that they are charges of negative electricity carried by particles of matter.”
About This Quote
Source Scientific Paper: "Cathode Rays", 1897
Thomson concluded that cathode rays are streams of negatively charged particles, later called electrons.
In simple terms: Cathode rays are negative particles.
