Question

Lithium metal crystallizes in a body centred cubic crystal. If the length of the side of the u cell of lithium is 351 pm, the atomic radius of lithium will be :

Answer 1

Atomic radius(r) =>

r = a×sq. root 3 /2

Where, a = edge length

a = 351 pm. (given)

So, r = 351 × sq. root 3 / 2

r = 303.97 pm.

Answer 2

Answer:

Explanation:

Since Li crystallises in body-centred cubic crystal, atomic radius, r = √3a/4 (a = edge length)llithium-metal-crystallises-body-centred-cubic-crystal-length-side-unit-cell-lithium-351
