5 days ago · Ernest Rutherford discovered in 1911 that every atom has a nucleus in its center. Protons that are electrically positive and neutrons that are electrically neutral makeup atomic nuclei. Who discovered electron neutron and proton: Electron by J.J. Thomson in 1897. Proton by Rutherford, Geiger, and Marsden in 1909. Neutron by James Chadwick in 1932.
3 days ago · The plum pudding model of the atom states that. an atom is made up of electrons in a sea of positive charges. the charged particles in the beams that Thomson studied came from atoms. As these particles moved away from their original atoms, they formed a visible beam. The current model of the atom includes protons, neutrons, and electrons.
4 days ago · Magnitude of positive charge is equal to the magnitude of negative charge and the atom as a whole is neutral. Limitations of this model are written below: 1 1. Thomson’s model couldn’t explain the stability of the atom. According to this model negatively charged particles are embedded in positive charge, but this model failed to explain how ...
6 days ago · What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment? The stream of cathode ray particles was moving very slowly. The glass opposite of the negative electrode started to glow. The electric voltage had little effect on the stream of particles.
