Calculate the number of atoms in a cube ...

Calculate the number of atoms in a cube based unit cell having one atom on each corner and two atoms on each body diagonal.

Text Solution

Verified by Experts

The correct Answer is:
`Z_(eff) = 9`
There are `4` diagonals of a cube.
`:.` Diagonal are in body centre and does not share.
Diagonal share `= 4 xx 2 = 8`
Corner share `= 8 xx (1)/(8) = 1`
`Z_(eff) = 9`
