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)

1.	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)
Answer» Solution :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)
