In general, the best conductors of electricity are metals, which share their valence electrons loosely; thus, allowing them to move freely. Usually, the fewer valence electrons (electrons in the outermost orbit), the better the conductor. But, there are some exceptions, such as: aluminum (has 3 valence electrons) is a better conductor than platinum (has only 1 valence electron). Silver is the best conductor; however, it's very expensive, so copper or aluminum are used in most wiring applications. Gold is not as good a conductor (Higher resistivity) as either Copper or Silver, but is less prone to corrosion, and so is used in hostile enviromnets, or for connectors; as well, but it has a relatively low melting point, giving it a tendency to melt.
A good non-metal conductor is carbon, but only when it's in the form of graphite. Tap water is another good, non-metal conductor.
It's worth remembering that the Manhattan Project, which ran during World War II, needed the best possible conductors for the magnetic cores they were designing. So, they requisitioned several TONS of silver from the US Treasury for the war effort.

Is chromium a good conductor or poor conductor?
All metals conduct electricity to some extent. Chromium isn't an especially good conductor, but it does conduct.. so we can say that it is a poor conductor.
Is sphalerite a good conductor of electricity?
No, sphalerite is not a good conductor of electricity. It is classified as a semiconductor, meaning it has some conductivity but not as high as good conductors like metals.

What are the best conductors of heat or electricity?
The best conductor of electricity is Silver, while the best conductor heat is helium (in its Helium II state), but some people consider diamond as the best heat conductor.
