• Conductivity means the ability of a material to allow the flow of electric current (movement of electrons or ions).

Types Of Solid Based On Conductivity

• Conductors

• Insulators

• Semi-Conductors

Solid Conductor

• The conductivity will be really high in conductor solid as they have the ability to allow the free flow of electrons

• In conductors, free electrons also called as delocalized electrons can move freely

• Example -: Metals, Copper And Silver

Solid Insulator

• Solid insulators means that the electrons are tightly bonded and there will be no space for free movement

• The conductivity will be really low as there will not be any delocalized electrons

• Example -: Wood And Rubber

Solid Semi-Conductors

• There will be few free electrons thus very small conductivity is possible

• The conductivity will be in a medium level

• Example -: Silicon
