But if your talking about pencil “lead” certainly silver is the better conductor. Silver is the best conductor, good conductivity and more suitable to use as electrical energy distribution. Chemistry. Gold has excellent electrical and thermal conductivity (compared to base metals such as aluminum or iron, etc.)
Which is good conductor of electricity gold or graphite?
Due to the presence of this one delocalised electron, graphite is a good conductor of electricity. However, graphite is the only non-metal that can conduct electricity. So, the correct answer is “Option A”.
