Answer:
neutrons are inside the nucleus
Explanation:
The most significant contribution that added to Rutherford's discovery of a positive nucleus is that neutrons are also inside the nucleus.
- The discovery of neutrons as a nuclear particle was instrumental to Rutherford's discovery.
- Since during his experiment, the alpha particles were deflected partly, he suggested a massive nucleus made up of just protons.
- With the discovery of the neutron, the mass of the nucleus was enough to cause the deflection.
