A certain metal crystallizes in a face-centered cubic structure.What is the edge length of the unit cell if the atomic radius of the metal is 144 pm?
A)204 pm
B)288 pm
C)333 pm
D)407 pm

Question

Quizplus · Accepted Answer

In a face-centered cubic (FCC) structure, the edge length (a) is related to the atomic radius (r) by the formula a = 2√2r. Substituting r = 144 pm, we get a = 2√2 * 144 pm ≈ 407 pm.
