In the later 1880s, JJ. Thomson experimented with cathode rays by bending them in an applied electromagnetic field. He discovered that the charge/mass (e/m) ration was the same no matter what the cathode was made of.
a what did this suggest?
b what were these particles called?
c. what model of the aton's structure did he propose?

a> Suggested that the rays were more fundamental in nature than elements. Further, these rays carried electric charge and the ratio of charge to mass is constant so it was a unique particle.
b. electrons
c. THompson thought the atom was a ball of positive and negative charges. SOmehow, one could pull electrons out of the atom. Rutherford disproved this model with a scattering experiment.
