What is a common property of non-metals?

Answer and explanation

Correct answer: They are generally poor conductors of electricity

The governing concept is the usual physical behavior of non-metals. Most non-metals lack the freely moving electrons that allow metals to conduct electricity efficiently, so they are generally poor electrical conductors. Option C states this common property. Option A describes the behavior of most metals, not non-metals. Option B is also mainly associated with metals, since non-metals are often dull, although there are exceptions. Option D is incorrect because non-metals are not metals and may be solids, liquids, or gases at room conditions. Graphite, an allotrope of carbon, is a well-known exception that conducts electricity.
