Defects in crystal: Stoichiometric Defects 1. On the basis of conductivity solids are classified in 3 types: Conductor, semi-conductor, insulator.

Their positions are shown as points. The edges may or may not be perpendicular to each other. Figure 16 Schottky defects appear generally in ionic crystals in which the positive and the negative ions do not differ much in size. The number of effective octahedral voids in a unit cell is equal to the effective number of atoms in that unit cell.

In the given solid, there is one B and four A per unit cell. Determing the void percentage of this solid. Determine the packing fraction of this solid. In the above solid, face centres are closer to body centre, therefore, the relationship. Determine the number of Ca atoms present on surfaces of a mm 3 block of calcium metal assuming that atoms in the closest packing calcium metal assuming that atoms are in the closest packing. The cylinder will pass through centre of middle layer and will lie between the face centres. Determine the packing fraction of this polymer in solid state assuming that molecules are in their closest contact. Given the ionic radii of Cs and Br - are 1. Determine atomic weight of titanium if density is 16. Also determine the number of unit cells present in a 5 cm 3 block of titanium metals. Determine the density of metal. Atomic mass of copper metal is 63. According to the given information, a view of one face of the unit cell will be as shown below. Determine the density of metal.

Sodium chloride, quartz glass, quartz, rubber, polyvinyl chloride, Teflon A. What is the formula of compound? There is evidently, a deficiency of the metal ions although the crystal as a whole is neutral. For example: ZnS, AgBr, AgI etc. Let us call this layer as the B layer. Thermal energy is also called Kinetic Energy and is responsible for motion of molecules inside solid lattice. Types Of Unit Cell A lattice can be generated by repeating a small portion called the unit cell. Irregular shape due to disordered arrangement of constituent particles. They are also known as simple unit cells. Crystal displays long-range structure made up of the same building block used over and over. For example, if some SrCl2 is added in molten salt of NaCl it takes the position of Na+ in the crystal. Generally a solid is defined as a substance which has rigidity, fixed shape, and size.
