🤓 Based on our data, we think this question is relevant for Professor Zhang's class at USF.
We are being asked to rank the given compounds in increasing magnitude of lattice energy. To estimate the lattice energy (or ionic bond energy) of an ionic compound, we will use the following equation:
Radius = period number
• To determine the cation and anion charge, recall that some elements have common charges based on what group they belong to on the periodic table:
Place the following in order of Increasing magnitude of lattice energy.
MgO NaI BaO
a. Nal < MgO < BaO
b. MgO < Nal < BaO
c. MgO < BaO < Nal
d. BaO < MgO < Nal
e. Nal < BaO < MgO
