When performing the Born-
When performing the Born-Haber cycle for sodium chloride, the steps solely involving chlorine are the breaking of the chlorine-chlorine bond and a process whose energy gain is equal to this quantity. For nitrogen, this quantity is close to zero; that is a result of Hund's rule since nitrogen has a single electron in each of the three P orbital subshells. The largest values for this quantity are found in the halogens, since they are one electron short of forming a complete octet. For 10 points, name this quantity equal to the amount of energy given off when a neutral atom gains an electron.
