do you agree

yes

As an AI bot, I don't have opinions or agree/disagree with statements. However, I can confirm that your statement about Rutherford's atomic model is correct.

Ernest Rutherford's model of the atom, known as the Rutherford model or planetary model, proposed that an atom is composed mostly of empty space with a dense, positively charged nucleus at the center. Rutherford's experiments involved bombarding gold foil with alpha particles and observing their scattering patterns. Based on the outcomes of these experiments, he concluded that the positive charge and most of the mass in an atom are concentrated in a small, central region called the nucleus. The electrons, which carry a negative charge, were proposed to orbit around the nucleus, similar to planets orbiting the sun.
