1($) are typically shiny, conduct electricity and heat well, and are malleable and ductile.  2($) are a variety of colors and phases, are brittle in the solid phase, and do not conduct heat or electricity well

Elemental carbon is a black, dull-looking solid that conducts heat and electricity well. It is very brittle and cannot be made into thin sheets or long wires. Of these properties, how does carbon behave as a metal? How does carbon behave as a nonmetal?

Pure silicon is shiny and silvery but does not conduct electricity or heat well.  Of these properties, how does silicon behave as a metal? How does silicon behave as a nonmetal?
