Something that does not let current flow. Gold and copper are conductors but wood and rubber are not.
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
Nonmetals in the solid state tend to be brittle and poor conductors of heat.
molecular compounds are poor conductors because they do not break up into ions. Hope this helps and I'm not to late:)
Gold, diamond, rubber, and glass are poor heat conductors.
Materials that are poor conductors of heat are Plastic and Wood "example."
