What is lattice energy?
I was going through my chemistry textbook when I encountered this very disturbing explanation on lattice energy. In this text, it seems like the writer is implying that for an ion pair in the gaseous state, ionisation energy (IE) and electron affinity (EA) can be used to measure it's stability. But even an ion pair in the gaseous state is held by an electrostatic force that gives it more stability, so more energy will be needed to separate the ion pair and that energy would be more than IE and EA. Pls I'm very confused by this pls I need someone to explain what the writer means.
