Concept explainers
(a)
Interpretation:Interpret the chemical formula of the ideal perovskite material. Perovskite material contains the element Y, Ba, Cu and O elements. They are superconductors at temperature above that of liquid nitrogen were recently discovered.
Concept Introduction:
Solids are composed of certain repeating basic units which are called as unit cells. These units represents the arrangement of atoms in a certain manner that repeats itself throughout the solid and make the crystal lattice.
Each solid has a different type of unit cell and crystal lattice that makes it unique from other solids. The atoms are arranged in unit cells.
(b)
Interpretation: The structure of ideal perovskite material needs to be interpreted as given in fig (b). Perovskite material contains the element Y, Ba, Cu and O elements. They are superconductors at temperature above that of liquid nitrogen were recently discovered.

Chemical Principles
- Describe, in general, the structures of ionic solids. Compare and contrast the structure of sodium chloride and zinc sulfide. How many tetrahedral holes and octahedral holes are there per closest packed anion? In zinc sulfide, why are only one-half of the tetrahedral holes filled with cations?arrow_forwardWhat is the coordination number of Cs in CsCl? of Na in NaCl? of Zn2 in ZnS?arrow_forwardWhich solid phase that is, which allotrope of carbon is more stable, graphite or diamond? You should consult some of the tables in the thermodynamics section of this text.. Both solid phases exist under normal conditions of pressure and temperature. Explain why this is so, given that one solid phase is more thermodynamically stable than the other. Do their unit cells provide any suggestion for their relative stabilities?arrow_forward
- Outline a two-dimensional unit cell for the pattern shown here. If the black squares are labeled A and the white squares are B, what is the simplest formula for a compound based on this pattern?arrow_forwardIn the LiCl structure shown in Figure 9.21, the chloride ions form a face-centered cubic unit cell 0.513 nm on an edge. The ionic radius of Cl- is 0.181 nm. (a) Along a cell edge, how much space is between the Cl- ions? (b) Would an Na+ ion (r=0.095nm) fit into this space? a K+ ion (r=0.133nm)?arrow_forwardA compound of cadmium, tin, and phosphorus is used in the fabrication of some semiconductors. It crystallizes with cadmium occupying one-fourth of the tetrahedral holes and tin occupying one-fourth of the tetrahedral holes ina closest packed array of phosphide ions. What is the formula of the compound? Explain your answer.arrow_forward
