Please answer question 16 part A and C

The electrostatic attraction between oppositely charged ions is called an ionic bond. The net energy change in the formation of an ionic bond is a composite of five steps, some of which absorb energy and some of which release energy. The steps are summarized for a generic metal, M, and a diatomic halogen, X2, as Part A The formation of CsCl from Cs(s) and Cl2 (g) involves the following steps: 1. sublimation of the metal, 2. dissociation of the X-X bond, 3. ionization of the metal, 4. transfer of the electron to X, and 5. crystalline solid formation. 1. Cs(s)→Cs(g) 2. Cl2 (g)→Cl(g) 3. Cs(g)→Cs+ (g)+e¯ 4. Cl(g) + e¯→Cl¯(g) 5. Cs+ (g) + Cl- (g)→CSCI(s) Which of these steps absorb energy and which release energy? The overall energy transfer is the sum of the energy changes for each step. The magnitude of the potential energy of two interacting charges, E, (which is related to Lattice energy) is the energy associated with the strength of the attraction between ions in the ionic compound and can be determined by Drag the items to the appropriate bin. • View Available Hint(s) Reset Help 1 91 × q2 E k d 4TE0 d where k is a constant equal to 1/(4T€0) = 1/(1.11 x 10-10 C² /(J . m)), q1 and q2 are the charges of the ions, and d is the 00000 1 2 3 4 5 distance between the nuclei of the ions.
