One of the deductions from Rutherford’s alpha particle scattering experiment is that?
- electrons are negatively charged
- electrons have a negligible mass
-
nuclei of atoms are positively charged
- protons are positively charged
The correct answer is: C
Explanation
The model of an atom put forward by Ernest Rutherford in 1911 on the basis of experiments on the scattering of alpha particles. The model consisted of a very dense positively charged nucleus, with electrons orbiting round the nucleus.
