Ernest Rutherford, in his atomic model, proposed that the atom consists of a tiny, dense, positively charged core (called the nucleus) in which nearly all the mass is concentrated, around which the light, negatively charged electrons circulate at some distance, much like planets revolving around the Sun.

The main deductions from his theory, such as the existence of a central charge and the orbital motion of electrons, are indeed independent of whether the central charge is positive or negative. This is because the deductions are based on the observations of the scattering of alpha particles, which are positively charged. These observations showed that most alpha particles passed through the atom with little or no deflection, while a few were deflected through large angles. This could be explained by a model in which most of the atom is empty space, with a small, dense, centrally located charge providing the deflection.

However, these observations did not allow Rutherford to conclude whether the central charge is positive or negative. This is because the alpha particles used in his experiments were positively charged, and would be deflected by a central charge of either sign. The direction of deflection would depend on the direction of motion of the alpha particles and the central charge, not their relative signs. Therefore, while Rutherford's experiments could determine the existence and location of the central charge, they could not determine its sign.

It was later experiments, particularly those involving the behavior of electrons in an electric field, that showed the central charge to be positive. This is because electrons, which are negatively charged, are attracted to a positive charge and repelled by a negative charge. Therefore, the behavior of electrons in an electric field could be used to determine the sign of the central charge.
