Write the name of a non-metal conductor of electricity?

Answer: Graphite, a form of carbon, is a non-metal that conducts electricity. Most non-metals are poor conductors of heat and electricity because they lack free electrons. However, graphite is an exception due to its unique atomic structure. This makes it one of the most important non-metal conductors used in daily life and industries.

Why Graphite Conducts Electricity

• Atomic Structure: Graphite consists of layers of carbon atoms arranged in hexagonal patterns.
• Free Electrons: Each carbon atom bonds with three others, leaving one electron free to move.
• Electron Flow: These free electrons allow graphite to conduct electricity, similar to metals.

Properties of Graphite

• Black, soft, and slippery solid.
• Good conductor of electricity.
• Insoluble in water.
• High melting point.

Uses of Graphite

• Electrodes: Used in batteries and electrolysis.
• Pencils: "Lead" in pencils is actually graphite mixed with clay.
• Lubricant: Reduces friction in machines.
• Nuclear Reactors: Used as a moderator to slow down neutrons.

Other Non-Metals That Conduct Electricity

Besides graphite, some forms of silicon and phosphorus (black phosphorus) can conduct electricity, but graphite remains the most well-known example.
