Rutherford used alpha radiation to bombard a thin foil of gold in order to discover a more accurate depiction of an atom. Alpha particles are the same as helium nuclei and thus have a positive charge. It was found that a few of the millions of alpha particles were strongly reflected or ricocheted. This means that there must be a small and positively charged area in an atom. This was the discovery of the nucleus.

Rutherford used alpha particles shot through gold foil.
An alpha particle is a helium nucleus (2 Protons and 2 Neutrons) with a charge of 2+.
Rutherford found most went through the thin gold foil, but some alpha particles were deflected a lot.
He concluded that most of the atom is empty space - allowing particles to go through the foil, but some dense + charged area (the gold atoms nucleus) would cause the deflections.
Hope this helps.

Rutherford did not bomb rays.
His experiment consisted of bombarding a gold foil with alpha particles.
Some of the particles went through, other deflected and some were deflected right back. This lead Mr. R to build a model of the atom that includes a center part full of positive charge.

alpha rays... they were the first rays found is why they are called alpha
