Textbook Question

Chapter 7, Problem 62IL

Spinets are solids with the general formula M²⁺ (M^′3+)₂O₄ (where M²⁺ and M^′3+ are metal cations of the same or different metals). The best-known example is common magnetite, Fe₃O₄ [which you can formulate as (Fe²⁺)(Fe³⁺)₂O₄].

Chapter 7, Problem 62IL, Spinets are solids with the general formula M2+ (M3+)2O4 (where M2+ and M3+ are metal cations of the

A crystal of a spinet

(a) Given its name, it is evident that magnetite is ferromagnetic. How many unpaired electrons are in iron(II) and in iron(III) ions?
(b) Two other spinets are CoAl₂O₄ and SnCo₂O₄. What metal ions are involved in each? What are their electron configurations? Are the metal ions paramagnetic, and if so, how many unpaired electrons are involved?
