Question

caesium and chloride ions are in contact along the body diagonal in a body centred cubic lattice .the edge lenght of the unit cell is 350pm and caesium has radius of 133pm. hence the radius of chloride ion is ?​

Answer 1

Answer:

Radius of Cl ion will be 175.79 pm.

Explanation:

In a body-centered cube lattice, for cesium chloride :

r = r ( cation ) + r ( anion )

r ( cation ) + r ( anion ) = √ 3 a/ 2

r (Cs+) + 181 = √3 x 141 / 2 = 356 . 79

r (Cl-) = 356.79 - 181 = 175.79 pm

Answer 2

Explanation:

so the ans is 170pm....
