Solid State 1
- Crystalline solids
- substances having same crystalline structure are called isomorphous
- single substance that crystallizes in two or more forms under different conditions are called polymorphous
- true solids
- may or may not be isotropic
- heat of fusion -definite depends on- arrangement of particles
- characteristics shape due to orderly regular long-range arrangement of constituent particle
- homogeneous solid in which constituent particles atoms ions are molecules are arranged in a definite repeating pattern
- classification
- molecular solids
- ionic solids
- metallic solids
- covalent solids
- high melting point and depending upon available availability of mobile electrons - conductors / insulators
- examples- Diamond graphite and fullerene
- MP of diamond 3550 degree Celsius
- graphite is used as lubricant &it is also used in Ribbons for printing in computers and typewriters, in lead pencils.
- fullerene + potassium---> K35 C60- superconductor at 18 Kelvin, tubes of fullerene + graphite> nanotubes >used as high strength materials, electric conductors, molecular sensors, semiconductors
- fullerene- soccer ball- Hollow sphere- C60.
- MP of diamond 3550 degree Celsius
- examples- Diamond graphite and fullerene
- high melting point and depending upon available availability of mobile electrons - conductors / insulators
- molecular solids
- substances having same crystalline structure are called isomorphous
- amorphous solids
- irregular shape due to short range orderly arrangement
- pseudo solids or cooled liquids
- isotropic like liquids
- heat of fusion is not definite
- substances that appear like solids but do not have well developed perfectly ordered crystalline structure
- irregular shape due to short range orderly arrangement
