Atoms were thought to be particles that could not be divided up into smaller particles.
By 1898, the electron had been discovered and the plum-pudding model of an
atom was proposed.
The results from experiments after 1898 led to the nuclear model.
Compare the position of the subatomic particles in the plum-pudding and nuclear
models.
