    This may be positive or negative, depending on the atoms involved and how they interact. Hess's Law states that the overall change in energy of a process can be determined by breaking the process down into steps, then adding the changes in energy of each step. The BornHaber Cycle is essentially Hess's Law applied to an ionic solid. Using the BornHaber Cycle. The values .
