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

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

 [A]. Both A and R are true and R is correct explanation of A [B]. Both A and R are true but R is not correct explanation of A [C]. A is true but R is false [D]. A is false but R is true

Explanation:

Atomic number is not dependent on lattice structure.

 Akanksha said: (Dec 20, 2016) Body centre cubic lattice : lattice point is at the centre of the unit cell (cube) in addition to the 8 corner points crystal structure.

 Sam said: (Jun 22, 2018) 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.

 Yaswi said: (Nov 22, 2018) 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.
