â€‹Q1 Radii of A+ and that of
X– and Y– have been given as
A+ = 1 00 pm
X– = 1 00 pm
Y– = 2 00 pm
Assign structure of AX and AY crystals and also determine the
volume of unit cells of AX and AY crystals
Ans Volume (a3 ) = 216 pm3

Dear Student

For first, crystal is bcc because radii of cation and anion are
equal

a=4r3=4*13=2 308volume= a3=12 29 pm3
For second,
