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

Q. A cubic unit cell has one atom on each corner and one atom on each body diagonal. The number of atoms in the unit cell is ________.

Q. A solid compound contains X,Y and Z atoms in a cubic lattice with X atoms occupying the corners, Y atoms in the body centred positions and Z atoms at the centre of the faces of the unit cell.
What are the total effective number of atoms ($Z_{eff}$) in a unit cell if all the atoms from a face diagonal of the lattice are removed?

Q. Atoms X,Y,Z crystallize in a cubic lattice where atom X occupies the corners of the cube and atom Y occupies the end-centred positions and Z occupies the body centre positions
What will be the simplest formula of the unit cell if one of the face diagonals containing end centre atom is removed?

Q. Given below are two statements labelled as Assertion (A) and Reason (R).
Assertion (A): There are two atoms per unit cell in bcc.
Reason (R): A body-centred cubic (bcc) unit cell has an atom at each of corners and also one atom at its body centre.
