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].
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?
