Conducting electricity or heat.
Yes.
Alloys are a combination of two or more elements. Not all alloys are poor conductors, in fact many are used specifically as conductors.
Poor conductors of heat are generally also poor conductors of electricity. These would include most gases, ceramics and man-made plastics. A vacuum will not conduct heat either.
- lower density- lower hardness- lower melting point- lower boiling point- some nonmetals are gaseous or liquidsetc.
good conductors are better emitters
Insulators.
insulators
most non ferrous materials are poor conductors with exceptions
molecular compounds are poor conductors because they do not break up into ions. Hope this helps and I'm not to late:)
Nonmetals in the solid state tend to be brittle and poor conductors of heat.
Gold, diamond, rubber, and glass are poor heat conductors.
