dedylja [7]

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.
