Thallium chloride (TICI) crystallizes in a cubic lattice whose edge length is found to be 385 pm. If the density of the solid is found to be ` 7.0 " g cm"^(-3)` , predict the type of lattice to which the crystals of TICI belong .
(Atomic mass of TI = 204, Cl = 35.5)

Text Solution

Verified by Experts

The correct Answer is:
BCC
Calculate Z. It comes out to be 1. This shows that a unit cell of TICI has one formula unit of TICI . Hence , it has body-centred cubic lattice (similar to that of CsCl)
