Assertion (A): Atomic number of sodium is 11.

Reason (R): Sodium has a body centred cubic lattice.

Both A and R are true and R is correct explanation of A
Both A and R are true but R is not correct explanation of A
A is true but R is false
A is false but R is true

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

Is that sodium had bcc lattice structure? Please tell me.

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.

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.
