Recall: In a unit cell, the atom in each corner is shared by 8 other unit cells. This means a unit cell has 1/8 of a corner atom.
Likewise, the atom at the edge of a unit cell is shared by 4 other unit cells, meaning the unit cell has 1/4 of an edge atom.
Lastly, the atom at the center of a unit cell is shared by only 1 unit cell, meaning the unit cell as 1 of a center atom.
One of the various manganese oxides crystallizes with a cubic unit cell that contains manganese ions at the corners and in the center. Oxide ions are located at the center of each edge of the unit cell. What is the formula of the compound?
