Answer:
Rutherford bombarded the doubly charged helium nucleus on a thin gold sheet. He noticed that most of he alpha particles went straight undeflected. This means most of the space inside atom is empty.
Very few alpha particles got deviated and very rare alpha particle(Around 1 in 20000) got bounced back. He came to conclusion that something positive is at the centre of atom that repelled alpha particles and then found that neutrons are at the centre of atom.
