Energía reticular - Wikipedia, la enciclopedia libre

The Born–Haber cycle is an approach to analyze reaction energies. It was named after the two German scientists Max Born and Fritz Haber, who developed it in 1919. It was also independently formulated by Kasimir Fajans and published concurrently in the same issue of the same journal. The cycle is concerned with … See more Formation of LiF The enthalpy of formation of lithium fluoride (LiF) from its elements lithium and fluorine in their stable forms is modeled in five steps in the diagram: 1.
