This attractive force is related to three factors. First, the distance between the electron and the nucleus affects the electrostatic attraction: the closer the electron the stronger the force. Second, the number of protons in the nucleus can affect the attraction of the electrons. The more electrons there are the greater the attraction. Finally, the electrons between the nucleus and the outermost electron are responsible for a repulsion called shielding. 1500 13 20 Atomie Murmber 1 Use the graph to list the ionization energies…
