Calculate the atomic radius in cm for the following: a. bcc metal with ao = 0.3226 nm. (enter your answer to three significant figures.) r = cm b. fcc metal with ao = 4.3992 å. (enter your answer to three significant figures.) r = cm

Explanation:

1) Edge length of the metal in BCC unit cell =

Atomic radius of the metal  atom = r

For BCC unit cell, relationship between edge length and radius is given as:

.

2) Edge length of the metal in FCC unit cell =

Atomic radius of the metal  atom = r

For FCC unit cell, relationship between edge length and radius is given as:

The atomic radius of the metal  atom in FCC unit cell is .
