7 Crystal Systems Of Solids
Remember this 'C TOM THR' (pronounce as 'see tom teacher)

C for Cubic
T for Tetragonal
O for Orthorhombic
M for Monoclinic
T for Triclinic
H for Hexagonal
R for Rhombohedral

A familiar example for each

Cubic: NaCl
Tetrogonal: TiO2
Orthorhombic: BaSO4
Monoclinic: NaHCO3
Triclinic: K2Cr2O7
Hexagonal: Graphite
Rhombohedral: KMnO4.

MOST ORDERED STRUCTURE: CUBIC

MOST DISORDERED : TRICLINIC

Structure resembling Matchbox: Orthorhombic
