Who is discovered electrons

Schematic diagram for the experiment that led to the discovery of neutrons by Chadwick. Various experiments showed that mass of the nucleus is approximately twice than the number of proton.

What is the origin of this additional mass? Rutherford postulated the existence of some neutral particle having mass similar to proton but there was no direct experimental evidence. Several theories and experimental observations eventually led the discovery of neutron. Mary B.

He knew that these fields will move particles from side to side, but don't have much effect on how a wave moves. In his experiments, the cathode rays bent over to one side, so Thomson knew the cathode rays must be made of some small particle, which he dubbed a "corpuscle. However, people quickly realized that electric current was in fact made of moving electrons.

Since electricity is the lifeblood of everything from computers to phones to microwaves, the electron turned out to be interesting to just about everybody. APS News Archives.
