__________________ is the outermost shell of an atom. The Valence shell
electrons in the valence shell are important because they
can be used to produce an electric current flow


________________________ is a material that has very little resistance Conductor
and allows electrons to easily move through. Examples:
silver**, copper, gold, aluminum, iron


______________________ is any material that has a very high Insulator
resistance and resists the flow of electrons. Examples:
glass, rubber, plastic, paper


_______________________ is materials that has conductivity Semiconductor
between conductor and insulator. Examples: carbon,
silicon


In a ____________________, an outside force can be applied to conductor atom
force the atom to lose or gain valence electrons.


____________________________are moved by force: chemical Electrons
reaction, friction, pressure, heat, light, or a magnetic field
