Question

16. _______ is the non-metal which is a good conductor of electricity.

Answer 1

Graphite is the non-metal which is a good conductor of electricity.

• Non metals are the materials that are poor conductor of electricity
• But there are a few exceptions like graphite being a non metal can conduct electricity.
• Graphite is an allotrope of carbon in which three electrons of one carbon are used up in making a bond whereas one electron remains free. This one free electron helps in the conductivity of electricity.
• Due to this one free electron graphite is soft and slippery and hence is used as a lubricant.

Therefore, graphite is the non-metal which is a good conductor of electricity.
