Revision Notes on Solid State
 
Classification of solids:
Crystalline and Amorphous solids:
 
Based on binding forces:
Bragg Equation:
nλ = 2dsinθ,
Where
 d= distance between the planes
 n = order of refraction
 θ= angel of refraction
 λ = wavelength
 
NEET Chemistry Solid State Revision Notes
 
Crystal Systems:
 Total number of crystal systems: 7
 Total number of Bravais Lattices: 14

NEET Chemistry Solid State Revision Notes-1

 

Number of atoms in unit cells.
Primitive cubic unit cell:
 
 Number of atoms at corners = 8×1/8 =1
 Number of atoms in faces = 0
 Number of atoms at body-centre: = 0
 Total number of atoms = 1

NEET Chemistry Solid State Revision Notes-2

Body-centred cubic unit cell:
 
• Number of atoms at corners = 8×1/8 =1
 Number of atoms in faces = 0
 Number of atoms at body-centre: =1
 Total number of atoms = 2
 NEET-Chemistry-Solid-State-Revision-Notes 1
Face-centred cubic or cubic-close packed unit cell:
 
 Number of atoms at corners = 8×1/8 =1
 Number of atoms in faces = 6×1/2 = 3
 Number of atoms at body-centre: = 0
 Total number of atoms = 4

Packing Efficiency
Packing Efficiency = (Volume occupied by all the atoms present in unit cell / Total volume of unit cell)×100

 NEET-Chemistry-Solid-State-Revision-Notes 3

 

Octahedral and Tetrahedral Voids:
Number of octahedral voids = Number of effective atoms present in unit cell
Number of tetrahedral voids = 2×Number of effective atoms present in unit cell
So, Number of tetrahedral voids = 2× Number of octahedral voids.
 
NEET-Chemistry-Solid-State-Revision-Notes 4
Defects in crystal:
Stoichiometric Defects
 
1. Schottky Defects
• Some of the lattice points in a crystal are unoccupied.
• Appears in ionic compounds in which anions and cations are of nearly same size.
• Decreases the density of lattice
• Examples: NaCl and KCl
 
2. Frenkel Defects
• Ion dislocate from its position and occupies an interstitial position between the lattice points
• Appears in crystals in which the negative ions are much larger than the positive ion.
• Does not affect density of the crystal.
• Examples: AgBr, ZnS
 
Non-Stoichiometric Defects
 
1. Metal Excess defect:
• Metal excess defect occurs due to
• anionic vacancies or
• presence of extra cation.
• F-Centres: hole produced due to absence of anion which is occupied by an electron.
 
2. Metal deficiency defect:
• Metal deficiency defect occurs
• Due to variable valency of metals
• When one of the positive ions is missing from its lattice site and the extra negative charge is balanced by some nearby metal ion acquiring two charges instead of one
