Lattice Energy is the energy required to combine gaseous ions into a solid, crystalline structure.
Concept #1: Understanding Exergonic & Endergonic Reactions
When dealing with the absorbing or releasing of energy in general then we use the terms endergonic & exergonic.
Concept #2: Understanding Lattice Energy
Example #1: For each pair, choose the compound with the lower lattice energy.
a. BaO or MgO
b. LiCl or CaS
Practice: Choose the compound with the lower lattice energy.
Practice: Choose the compound with the higher lattice energy.
