Lithium forms body centred cubic structure. The length of the side of its unit cell is 351 pm . Atomic radius of the lithium will be:

Solution & Step-by-step Explanation

For a body-centered cubic (BCC) lattice, the relationship between edge length (a) and atomic radius (r) is: 3 a = 4 r Given a = 351 pm : r = \frac{3 \times 351}{4} = \frac{1.732 \times 351}{4} \approx 151.98 pm Rounding off, we get 152 pm .

Try it yourself before checking the explanation above.
