Distinguish between cations and anions.

CsBr has bcc structure with edge length of 43 pm . The shortest interionic distance between cation and anion is

In zinc blende structure anions are arranged in ccp and cations are present in the tetrachedral voids and only half the tetrahedral voids are occupied, if 'a' is the edge length of the unit cell then for zinc blende structure the distance of closest approach between cation and anion is

Differentiate between cationic and anionic detergents giving suitable examples.
