There are Z protons in the nucleus of an atom, where Z is the atomic number of the element. An 𝛼 particle carries a charge of +2e. In a scattering experiment, an 𝛼 particle, heading directly toward a nucleus in a metal foil, will come to a halt when all the particle’s kinetic energy is converted to electric potential energy. In such a situation, how close will an 𝛼 particle with a kinetic energy of 5.0 × 10−13 J come to a gold nucleus (Z = 79)? Apr 25 2022 08:13 PM
