Types of Solids

Crystalline solids

• Have repeating patter of particles.

• 3-D pattern= "crystal lattice"

• Defined MP

• Most solids

  Amorphous Solids

• Glass and plastic

• No repeating pattern of particles

• No defined MP

  ionic Solid

• Et: Table Salt

• Lattice particles → ions

• Bands → ionk

• High MP

• Conductivity When liquid or aqueous

Molecule solid

• Ex- water and sugar

• Lattice Particles → molecules

• bonds → IMFS

• High MP

• conductivity → non conductable

  Network solid

• EX: diamonds , graphite SO2 (quartz)

• Lattice particles → atoms

• Bonds → covalent

• Very high MP

• Conduct → non-conductive

  Metallic Solid

• EX: Fe, Cu

• lattice particles → sea of valence electrons

• High to Low MP

• Conductivity when solid or molten
