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.

(c)
Interpretation: The empirical formula of the structure needs to be determined which is given in fig (b) for ideal perovskite material 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.
