Download Solution PDFThe correct answer is 'Plastic, wood and rubber'.Key Points
- Insulators are materials that do not have free electrons, therefore they do not conduct electricity.
- Some examples of insulators are Sulphur, Mika, and Polythene.
- Plastic, wood, and rubber don't have free electrons moving around so they can't conduct heat and electricity which gives them the property of good insulators.
- Most non-metal materials such as plastic, wood, and rubber are insulators.
Additional Information
- Steel is a conductor because it is an inflexible and highly corrosive metal when exposed to air.
- Iron has metallic bonds which are where the electrons are free to move around more than one atom.
- This is called delocalization. Because of this, iron is a good conductor.
