Question

Calculate exchange energy for d3

Answer 1

Answer:

The exchange energy is the energy which makes stable electronic configaration of the elements. Altough only Exchange energy can't explain to the all elements,their also repulsion energy,orbital transfer energy also act as major cause of the electronic configaration of the elements.

we can calculate the exchange energy in Mathematically but orbital transfer energy and repulsion energy are not calculated like exchange energy. Let the calxulate exchange of Ni

In case of nickel,the 3d subshell containes 8 electrons which 5electrons are up on spin and 3 electrons are down spin so 5 electrons can exchange with another one and 3 electrons also can exchange with another one. But the two electrons of 4s subshell,they are not exchange due to their spin are different. So the exchange energy

(5C2+3C2)k=13k
