2. The CsCl structure has a cubic unit cell that contains Clanions at the corners and a Cs* cation in the center. This unit cell is commonly, and mistakenly refered to as "body-centered cubic". Why is it not body-centered cubic. A. Actually, this is not a mistake. It is body-centered cubic B. Because the cations must be on the corners and anion in the center in order to be called body centered cubic. This arrangement is anti-body-centered cubic. C. Because...

What is the total number of ions (Na+ and Cl-) that lie within the NaCl unit cell? A) 2 B) 4 C) 8 D) 6 E) 5 -If you can explain to me the reason for the correct answer. Thank you
The metal potassium crystallizes in a body centered cubic unit cell with one atom per lattice...
The metal potassium crystallizes in a body centered cubic unit cell with one atom per lattice point. When X-rays with λ = 1.937 Å are used, the second-order Bragg reflection from a set of parallel planes in a(n) potassium crystal is observed at an angle θ = 21.32°. If the spacing between these planes corresponds to the unit cell length (d = a), calculate the radius of a(n) potassium atom.
