🤓 Based on our data, we think this question is relevant for Professor Kachur's class at USP.
The relative lattice energy can be estimated using the equation below:
As we can see from the equation the charge and the radius affects the Lattice energy.
The trend is shown below with the elements in the compounds below written on the table:
Would you expect salts like NaCl, which have singly charged ions, to have larger or smaller lattice energies compared to salts like CaO, which are composed of doubly charged ions?
