Alpha particles (a) were shot toward a gold foil. Gold has an atomic number of 79. An a had initial kinetic energy of about 6.1 MeV. When an a was closest to a gold nucleus, it stopped completely by the electric repulsive force between the two nuclei. Assume all the a kinetic energy was converted to electric potential energy. The closest distance (center to center) between the two nuclei isx 10-15 meter. Ch. 19.3, 33 Type your answer...
