Unit cell is the repeating unit of a crystal. This tells what the composition of the entire lattice system
From given diagram, Xe atoms are located at the 8 corners and 1 in the center of the unit cell.
On the other hand, 8 O atoms are present at the edges with 2 Os inside the cell
Each corner contributes 1/8th atom to the unit cell and each edge is 1/4 of the unit cell. Number of Xe and O atoms in 1 unit cell can be calculated as:
The unit cell for a pure xenon fluoride compound is shown below. What is the formula of the compound?
