Answer:
b. 295 pm
Step-by-step explanation:
To answer this question we need to use the equation of a face-centered cubic laticce:
Edge length = √8 R
Where R is radius of the atom.
Replacing:
417pm = √8 R
R = 147.4pm is the radius of the atom
As diameter = 2 radius.
Diameter of the metal atom is:
147.4pm* 2 =
295pm
Right answer is:
b. 295 pm
