good conductors are better emitters
Metals are good conductors of electricity, two of the best conductors are silver and copper.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.

Metals, in general. Copper and silver are particularly good conductors.
All metals are solids and good conductors apart from Mercury which is a liquid but is a good conductor.
They aren't necessarily good conductors of both (like diamond, which is a good conductor of heat, but not electricity) Graphite is one that is both, but most of them are metals.
Still air is an excellent thermal insulator, and the layers of newspaper are poor conductors, thus the ice cream carton will keep about as cool as you can get without using extra refrigeration.
These are good conductors-most metals are good conductors.
All metals are pretty good conductors of electricity.
