Please keep your answers simple since I am only doing A-Level physics. At least 1 out of every 12,000 particles rebounded. Protons and neutrons weigh much more than the tiny electrons; hence almost all the mass of a nucleus is centred around the nucleus. In nuclei, nucleons exists in nuclear energy levels and in atoms, electrons exist in atomic energy levels. The size (volume) of the nucleus is tiny compared to the size The diameter of the nucleus is in the range of 1.70 fm (1.701015 m) for hydrogen (the diameter of a single proton) to about 11.7 fm for uranium.

The size of a silicon nucleus is of the order of 0.117 nanometers. How do we know that the nucleus isn't a quark-gluon plasma? So the way I approached this was to consider $$\frac{E_a}{E_n}=10^{-6}\Rightarrow \frac{\frac{h^2}{8m_aL_a^2}}{\frac{h^2}{8m_nL_n^2}}=\frac{m_nL_n^2}{m_aL_a^2}=10^{-6}\Rightarrow \frac{L_a}{L_n}=\sqrt{10^6\cdot m_n/m_a }.$$The mass of the nucleus we assume to be 1u but what about the mass of the atom? University of Illinois at Urbana-Champaign, Volume measurement of irregularly shaped objects.

From what I've heard (from people who know this business), the current state of the art in lattice QCD computations is calculating the mass of the proton with some accuracy. That translates into the fact that the nucleus takes up particles are much heavier compared to protons; hence he was expecting them to deflect only slightly by the gold atoms subatomic particles. Use this info and the particle in the box model to make an order of magnitude estimate of the ratio $$\frac{\text{size of atom}}{\text{size of nucleus}}$$. Thermodynamically possible to hide a Dyson sphere? The proton count of a nucleus determines it as an atom of a specific element. Since the number of particles that got slightly deflected was very few, it was concluded that the charge of the atom occupied a tiny space.
