<p>Rutherford's Atom Model proposed that every atom consists of a tiny central core called the atomic nucleus, where the entire positive charge and almost the entire mass are concentrated. The size of the nucleus is very small compared to the size of the atom. The atomic nucleus is surrounded by a certain number of electrons, maintaining the overall electrical neutrality of the atom.</p> Signup and view all the answers

<p>The observations of Rutherford's Alpha Scattering Experiment indicated that most alpha particles passed straight through the gold foil, suggesting that most of the space in an atom is empty. Some alpha particles were scattered by small angles, indicating the presence of a small, positive region within the atom. A few alpha particles were deflected through large angles, indicating the presence of a concentrated positive charge at the center of the atom, known as the nucleus.</p> Signup and view all the answers

<p>Rutherford's Atom Model proposes that the entire positive charge and almost the entire mass of an atom are concentrated in a tiny central core called the atomic nucleus. This implies that the positive charges and most of the mass of the atom are concentrated at the center, while the rest of the atom is mostly empty space.</p> Signup and view all the answers

<p>Coulomb's force of repulsion refers to the electrostatic force between two positively charged particles, such as alpha particles and the positively charged nucleus. In Rutherford's experiment, alpha particles that traveled directly towards the nucleus were retarded due to this force and ultimately deflected, resulting in the observation of large angle deflections.</p> Signup and view all the answers

<p>According to Rutherford's Atom Model, the size of the atomic nucleus is of the order of $10^{-15}$ m, which is very small compared to the size of the atom, which is of the order of $10^{-10}$ m. This implies that the nucleus occupies a very small fraction of the total volume of the atom.</p> Signup and view all the answers
