Which substance do you expect to have the greatest lattice energy: MgF2, CaF2, or ZrO2? Why<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n Among the given substances, ZrO\u2082 (zirconium dioxide)<\/strong> is expected to have the greatest lattice energy. This is due to the combination of the following factors:<\/p>\n\n\n\n Lattice energy increases with the magnitude of ionic charges. ZrO\u2082 consists of Zr\u2074\u207a cations and O\u00b2\u207b anions, which have higher charges compared to the Mg\u00b2\u207a and Ca\u00b2\u207a cations in MgF\u2082 and CaF\u2082, and the F\u207b anions in these compounds. The greater charges in ZrO\u2082 create a stronger electrostatic attraction, significantly increasing the lattice energy.<\/p>\n\n\n\n Lattice energy is inversely proportional to the sum of the ionic radii of the interacting ions. Zirconium ions (Zr\u2074\u207a) are smaller compared to Mg\u00b2\u207a or Ca\u00b2\u207a due to the high charge-to-radius ratio, which results in stronger Coulombic forces. Additionally, oxygen ions (O\u00b2\u207b) are slightly larger than fluoride ions (F\u207b), but the overall effect of the smaller Zr\u2074\u207a radius dominates.<\/p>\n\n\n\n While MgF\u2082 and CaF\u2082 are largely ionic, ZrO\u2082 has partially covalent characteristics due to the polarizability of the oxygen ion and the high charge density of Zr\u2074\u207a. This enhances the overall lattice energy by increasing bond strength.<\/p>\n\n\n\n The lattice energy of ionic compounds depends on the charges of ions and their sizes. ZrO\u2082 has ions with higher charges (Zr\u2074\u207a and O\u00b2\u207b) compared to MgF\u2082 (Mg\u00b2\u207a and F\u207b) and CaF\u2082 (Ca\u00b2\u207a and F\u207b). Additionally, the smaller ionic radius of Zr\u2074\u207a contributes to a stronger electrostatic attraction, resulting in the greatest lattice energy for ZrO\u2082. The greater ionic charge and reduced ionic size in ZrO\u2082 lead to significantly stronger interactions, making its lattice energy the highest among the three compounds.<\/p>\n","protected":false},"excerpt":{"rendered":" Which substance do you expect to have the greatest lattice energy: MgF2, CaF2, or ZrO2?
