How many electrons are present in the 3d orbitals of the met

How many electrons are present in the 3d orbitals of the metal ion Co⁺?

Number of 3d electrons =

What is the ligand field stabilization energy of Co⁺ ion in a tetrahedral ligand field? Enter your answer in Dq units (the negative sign is already present).

LFSE = - Dq

Solution

Number of 3d electrons present in Co+ = 7 electrons

LFSE of Co⁺ ion in a tetrahedral ligand field = -6/45 (10 Dq)

= -0.267(10 Dq)

    = -2.67 Dq
