1.	The arrangement of X^(-)ions around A^(-)ion is solid AX is given in the fig (not drawn to scale) If the radius of X^(-) is 250 pm, the radius of A^(+)is
Answer» 104 pm 125 pm 183 pm 57 pm Solution :Cation`A^(+)`OCCUPIES octahedral VOID FORMED by anion `X^(-)` RADIUS of octahedral void = `0.414times"Radius of the anion packing"` =`0.414times250 "pm"` =`103.5 "pm"cong104 "pm"`
