Which of the following is a typical physical property of most non-metals?
AExcellent conductors of electricity
BAlways found as liquids at room temperature
CPoor conductors of electricity and often brittle if solid
DMalleable and shiny
Explanation
Most non-metals are poor conductors of electricity and heat, and solid non-metals, like sulfur, tend to be brittle rather than malleable. Non-metals can exist in all three states of matter at room temperature, including gases like oxygen and nitrogen, solids like carbon, and the liquid bromine. Despite generally being poor conductors, one important exception is graphite, a form of carbon that conducts electricity well due to its unique layered structure.
