Definition of body-centred cubic lattice?
The body-centred cubic unit cell has atoms at each of the eight corners of a cube (like the cubic unit cell) plus one atom in the centre of the cube (left image below). Each of the corner atoms is the corner of another cube so the corner atoms are shared among eight unit cells.

NaCl - has face centre cubic lattice which has 6 NaCl for unit cell.
THEREFORE EVEN ATOM CAN HAVE CUBIC LATTICE.
THEN CUBIC LATTICE OF Mg.
There are 8 types of unit cell which is an answer.

Atomic number is the number of protons/number of electrons. In sodium number of protons =number of electrons =11 so atomic number is 11.
And it is not dependent on crystal lattice.

Body centre cubic lattice : lattice point is at the centre of the unit cell (cube) in addition to the 8 corner points crystal structure.
