    The main conclusion of the α-particle scattering experiment, conducted by Ernest Rutherford, is that atoms consist of a tiny, dense, positively charged nucleus at the center, containing most of the atom’s mass, with electrons orbiting in the surrounding empty space. This led to the development of the nuclear model of the atom.

  3. 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

    The energy difference during an electron’s transition is emitted as electromagnetic radiation because it arises from changes in the electron’s energy levels, governed by quantum mechanics. Other forms of energy, like kinetic or thermal energy, do not align with the quantized nature of electronic transitions.
