The distance of closest approach is the minimum distance between the nucleus and an incoming particle, such as an alpha particle, during a collision. At this point, the particle's kinetic energy is completely converted into electrostatic potential energy due to the nucleus's repulsion. For more visiRead more

(i) Stability Issue: According to classical electromagnetic theory, electrons revolving around the nucleus should emit energy continuously, causing them to spiral into the nucleus. This contradicts the stability of atoms.
(ii) Spectral Lines: The model could not explain the discrete spectral lines observed in atomic emission or absorption spectra. It failed to account for the quantized energy levels of electrons, later addressed by Bohr’s atomic model.
Ionization energy is the energy required to remove an electron from an atom in its ground state. Replacing the electron with a 200-times heavier particle would significantly increase ionization energy, as reduced mass and energy levels increase.

The ratio of their nuclear densities is 1:1. Nuclear density is nearly constant for all nuclei because it depends only on the nuclear volume and not on the mass number, which scales proportionally with volume.
