Define crystal field splitting energy. On the basis of crystal field theory, write the electronic configuration for `d^(4)` ion if `Delta_(0) lt P`.

Text Solution

Verified by Experts

Crystal field splitting energy : It is the magnitude of difference in energy between two sets of d-orbitals i.e., `t_(2g)` and `e_(g)`.
Electronic configuration for `d^(4)` if `Delta_(0) < P : t_(2g)^(3) e_(3)^(g)`
