Question

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

Answer 1

Hii dude....

Here is ur answer...

There are 4 body diagonals in a cube.

There are two atoms in each diagonals.

Hence total no. of atoms atoms on the diagonal is 4×2=8

These 8 atoms are within the body of the cubic unit cell and are not shared by any other units.

The contribution of 8 corner atoms 8×18=8

therefore total no. of atoms in the unit cell = 8+1 = 9

HOPE THIS HELPS...
