The significant result deduced from Rutherford’s scattering experiment is that :

there are neutrons inside the nucleus α-particles are hydrogen nuclei the whole of the positive charge is concentrated at the centre of an atom electrons are embedded in the atom

the whole of the positive charge is concentrated at the centre of an atom

The significant result deduced from Rutherford’s scattering experiment is that the whole of the positive charge is concentrated at the centre of an atom and is called the nucleus.
