Rutherfords alpha scattering experiment.

Rutherfords explanation.
As a particles are positively charged, the
nucleus must contain positively charged protons.
All these a particles pass straight through the
empty space that makes up most of the atom.

As only 1 in every 20 000 a particles are
repelled the nucleus must be very small.
