How much is the length of Cs+ cation when Chloride ion is 1.81 Armstrong?(Cell parameter a=4.124 Armstrong)
Homework Answers
Answer)
CsCl structure type is bcc.
Cl- anion is located at the corner of the lattice
Cs+ cation located at the center of the lattice
Cell parameter (a) =2/ 
3 (radius of
Cs+ + radius of Cl-) = 4.124 
radius of Cl- = 1.81
(radius of Cs+ + 1.81 ) = 4.124 x
3 /2 = 3.571
radius of Cs+ = 3.571 - 1.81 =
1.761

In crystals of the salt cesium chloride, cesium ions Cs+ form the eight corners of a cube and a chlorine ion Cl- is at the cubes center. The edge length of the cube is L = 3.5 x 10^-10 m. The Cs+ ions are each deficient by one electron( and thus each has a charge of +e) and the Cl+ has one excess electron (and thus has a charge of -e). (a) if one of the Cs+ ions is missing...

Determine the coordination number for each ion: How many ions of each type are within one unit cell? Determine the face diagonal distance between the corner anions in the zine blend structure(figure B). Express this distance as a function of the cation and anion r_c and r_a that make up the crystal. Use this distance to determine the unit cell edge length, A, in terms of r_c and r_a. Given a Zn^2+ radius of 82 pm and aS^2-...
