1.	AB crystallizes in a body centredcubic lattice with edge length 'a' equal to 387 pm. The distancebetween two oppositely charged ions in the lattices is
Answer» 250 pm 200 pm 300 pm 335 pm Solution :For BODY CENTRED CUBIC (b.c.c.) lattice, DISTANCE between two oppositely CHARGED ions `d=(sqrt3a)/2 = (sqrt3times387)/2"pm"=335.15"pm"`
