according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
J.J Thomson proved the existence of a particle called an electron which is smaller than an atom and has a negative charge.
J.J. Thompson Discovered The Properties Of The Electron.
What did J. J. Thompson discover that had a negative charge?
He discovered the electron.
This particle was the electron in 1897 (J.J. Thomson).
J.J.Thomson was a physicist. He is credited with discovery of the electron based on his work with the cathode ray. He essential established the first sub-atomic particle.
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
The atom is the smallest known particle.
Neutron
J. J. Thomson discovered the electron (particle carrying negative charge) in 1897.
