Question

Which contribution added to rutherfords discovery of a positive nucleus atoms are invisible electrons are scattered in an atom neutrons are inside the nucleus of An atom atoms of the same element have the same properties

Answer 1

neutrons are inside the nucleus

Step-by-step 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.
