Arsenic. (5 marks). (b) When gold foil is bombarded by alpha particles it is found that most of the particles pass through the foil without significant change of direction or loss of energy. A few particles are deviated from their original direction by more than 90°. Explain, in terms of the nuclear model of the atom and by considering the nature of the forces acting,. : rays are high-energy photons, i.e. particles of electromagnetic radiation, like x-rays, but with higher energy, and more dangerous, with much greater penetrating power. x-rays in medical applicat .
