Question

1) state the general structure of spinels , including a picture of the unit cell. Use a T in a circle for the occupied tetrahedral hole(s) and oh in a circle for the occupied octahedral hole(s)
b) examine the trend in unit cell size of these group of spinels and relate it back to the identities of the cations present in each spinel. Explain how ion soze influences unit cell size .
C) predict other likely cations (including charge) that may be incorporated into a spinel structure , based on periodic trends .
