J.J. Thomson's cathode ray tube experiment demonstrated that:

Options

  1. Acathode rays are streams of negatively charged ions
  2. Ball the mass of an atom is cssentially in the nucleus
  3. Cthe e / m of electrons is much greater than the e / m of protons
  4. Dthe e / m ratio of the cathode-ray particle changes when a different gas is placed in the discharge tube

Correct answer

C. the e / m of electrons is much greater than the e / m of protons

Step-by-step solution

( e m )_ clectron ( e m )_ proton [ ( e m )_ protons = 1 1837 ( e m )_ electron ]
