What is the edge length of a face-centered cubic unit cell made up of atoms having a radius of 125 pm?
A) 177 pm
B) 354 pm
C) 500 pm
D) 1000 pm
E) 800 pm

Question

Quizplus · Accepted Answer

The edge length of a face-centered cubic unit cell (FCC) can be determined using the formula:
a = 2 * radius * √2
where a is the edge length of the unit cell.
Substituting the given value of the radius, we get:
a = 2 * 125 pm * √2
a = 354 pm (approx)
Therefore, the best choice is B) with an edge length of 354 pm.
