Answer 2

9

The exchange energy of d9 system​ is 9

$\frac{n(n-1)}{2}$ = $\frac{9(9-1)}{2}$ = 9

• Exchange = $\frac{n(n-1)}{2}$

                                              or

• Exchange Energy = $\frac{(Number of Electron(Number of Electron-1))}{2}$ is the formula for the energy released as a result of an exchange in location of electrons with the same spin.
• The total number of electrons in the atom's shells is known as the number of electrons.

When two or more electrons with the same spin are present in a subshell's degenerate orbitals, the stabilising effect occurs. These electrons frequently swap locations, and the energy produced as a result is known as exchange energy. The greatest number of exchanges is possible when the subshell is either halfway or fully filled. As a result, both the stability and the exchange energy will be at their maximum.
