uppose a chemist discovers a new metallic element and names it "Xiguum" (Xi).Xi exhibits chemical behaviour similar to an alkaline earth. Xi(s) + Cl2(g) → XiCl2(s)   Lattice energy for XiCl2 -1900. kJ/mol First Ionization energy of Xi  400. kJ/mol Second Ionization energy of Xi  680. kJ/mol Electron affinity of Cl -348.7 kJ/mol Bond energy of Cl2  239 kJ/mol Enthalpy of sublimation (atomization) of Xi      150. kJ/mol Use the above data to calculate ΔH°f for Xiguum chloride.

The charges and sizes of the ions in an ionic compound affect the strength of the electrostatic interaction between the ions and thus the strength of the lattice energy of the ionic compound. Arrange the compounds according to the magnitudes of their lattice energies based on the relative ion charges and sizes. Highest lattice energy Lowest lattice energy Answer Bank KCI MgO NaF MgF₂

Predicting the relative lattice energy of binary ionic compounds In each row, pick the compound with the bigger lattice energy. Note: lattice energy is always greater than zero. Which compound has the bigger lattice energy? BaCh BaS Bel₂ KF O BeBr₂ CsF O 1/5
