Zinc sulphide crystallises with zinc ions occupying half of the tetarhedral holes in a lclosest packed array of sulphide ions. What is the formula of zinc sulphide?

In a compound oxide ions have CCP arrange ment. Cations A are present in one-eighth of the tetrahedral holes and cations B occupy half of the octahedral holes. The simplest formaula of the compound is

A spinel is an important class of oxide consisting two types of metal ions with the oxide ions arranged in ccp layers . The normal spinel has one -eight of the tetrahedral holes occupied by one type of metal ions and one- half of the octahedral holes occupied by another type of metal ion. Such a spine is formed by Mg^(2+), Al^(3+) and O^(2-) . The neutrality of the crystal is being maintained. Type of hole occupied by Al^(3+) ions is:
