To determine the magnetic moment of \( \text{Co}^{2+}\text{Fe}^{3+}_2O_4 \), which has an inverse spinel structure, we need to consider the electron configuration and the spin states of the metal ions involved. ### Step 1: Determine the oxidation states and electron configurations - \( \text{Co}^{2+} \) has an electron configuration of \( [Ar] 3d^7 \), which means it has 7 electrons in the \( 3d \) orbital. - \( \text{Fe}^{3+} \) has an electron configuration of \( [Ar] 3d^5 \), meaning it has 5 electrons in the \( 3d \) orbital. In the inverse spinel structure, the metal cations are arranged so that the Co\(^{2+}\) ions ___ ________ ________ ______ ______ _____ ________ ______.
