The following four spheres represent a Na atom,a Na⁺ ion,a Cl atom,and a Cl^- ion,not necessarily in that order.Use your knowledge about the relative sizes of atoms,cations,and anions to determine which of the following sets of reactions is most consistent with the sizes of the atoms and ions shown below. A)A → B + e^- and C → D + e^- B)A → B + e^- and D → C + e^- C)B → A + e^- and C → D + e^- D)B → A + e^- and D → C + e^-

The relative sizes of Na and Na⁺ ion suggest that the ion is larger than the atom. The relative sizes of Cl and Cl^- ion suggest that the ion is smaller than the atom. This means that Na atom may lose an electron to form Na⁺ ion, and Cl atom may gain an electron to form Cl^- ion, as the resulting ions would have the expected sizes. Therefore, A is the most consistent set of reactions with the given sizes of atoms and ions.
