How did jj thomson discover electron

Web11 de jul. de 2024 · J.J. Thomson is credited with discovering the electron and its characteristics through tests conducted in a discharge tube. Subatomic particles with an elementary charge of -1 are known as electrons. The charge held by an electron is the same as the charge held by a proton (but has an opposite sign).
