Question #134988

Thallium bromide (TlBr) has a cesium chloride (CsCl) crystal structure.

i. Draw a unit cell of TlBr and determine the coordination number of Tl+ and Br- ions.

ii.Determine in which cubic form the TlBr occurs.

iii.Calculate the total number of ions in the cell unit.

iv. It is true that the edge length (a) of this crystal lattice is 2.31 times the radius (r) of the ions in the crystal? Justify your answer.

v. If the crystal has edge length (a) of 36.5 cm, calculate density of the crystal.
