Question

The significant result deduced from the Rutherford�s scattering experiment is that

• A. whole of the positive charge is concentrated at the centre of atom
• B. there are neutrons inside the nucleus
• C. $\alpha$-particles are helium nuclei
• D. electrons are embedded in the atom

Answer 1

Answer: (A)

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

Answer 2

On the basis of the observations of $\alpha$ particles scattering experiments, Rutherford presented a model of atom, called 'Rutherford's model'. this model, the mass of the atom (leaving the mass of its electrons) and its whole positive charge are concentrated at the centre of the atom.
