Basic Electricity Conductors and Insulators

What is the main factor that determines whether a material is a good conductor or insulator?

• The arrangement of protons in the atoms

• The arrangement of electrons in the atoms

• The number of neutrons in the atoms

• The number of shells in the atoms

Which type of atom is considered a good conductor of electricity?

• An atom with a filled outer shell

• An atom with only one electron in the outer shell

• An atom with two electrons in the outer shell

• An atom with no electrons in the outer shell

What is the term used for materials that have free electrons available to carry electrical energy?
