This document gives details of how the Born Haber Cycle of Sodium Chloride can be calculated. It includes the drawing of the Born Haber Cycle and the lattice enthalpy of Sodium Chloride.

I achieved a high A* Grade in my final A-Level exams using these notes!!! I believe you can achieve an A* if you can memorise these notes! Simply use blurting, a method of active recall, to write everything you remember from the notes, then identify the parts you couldn’t remember, then repeat until you can remember it all! If you can do that, you’ve got an A* in the bag! They are clear, concise, and are laid out according to the specification; there is no information missing or in excess...
