Cr³⁺ has the electronic configuration ([Ar],3d^3). In an octahedral crystal field, the five d-orbitals split into three lower-energy (t_{2g}) orbitals and two higher-energy (e_g) orbitals. The three electrons occupy the lower (t_{2g}) orbitals singly according to Hund's rule, giving the configuration (t_{2g}^3e_g^0). In a tetrahedral crystal field, the splitting is reversed, with the lower (e) orbitals and higher (t_2) orbitals. The three electrons are distributed as (e^2t_2^1). Mn²⁺ has the electronic configuration ([Ar],3d^5). In an octahedral field, whether the field is weak or strong, the half-filled d-shell is highly stable. The high-spin configuration is (t_{2g}^3e_g^2), with all five electrons remaining
