A new compound, boganium sulfide, has been discovered. X-ray crystallographic studies reveal that it has a cubic unit cell with a sulfide ion at each of the corner lattice points, a sulfide ion at the geometric center of the unit cell, and a boganium ion in the center of each of the cube faces in the unit cell. Based on this structure, the formula for the compound should be

Question

Quizplus · Accepted Answer

The unit cell contains 1 sulfide ion at the center, 1 sulfide ion from the corners (8 corners x 1/8), and 3 boganium ions from the faces (6 faces x 1/2), giving the formula Bo₃S₂.
