So, in my textbook, it says "The energy required to separate one mole of the ions of an ionic compound is referred to as lattice energy. The strength of the forces holding ions in place is reflected by the lattice energy. The more negative the lattice energy, the stronger the force of attraction" So, the second/third sentence is saying the lower the lattice energy, the stronger the bond? Would it not make sense if it was the other way around? Like, the more energy required to separate an ion from something means the bond is stronger, no?
