Which physical test can be used to distinguish between a metal element and a non-metal element?
One physical test that can be used to distinguish between a metal element and a non-metal element is the ability to conduct electricity. Metals generally conduct electricity well, whereas non-metals are poor conductors. Another test is the luster or appearance - metals are usually shiny and have a metallic luster, while non-metals are dull in appearance.
Are most metal elements brittle and don't conduct electricity?
Most metal elements are not brittle and do conduct electricity. However, there are exceptions, such as bismuth and mercury, which are brittle or poor conductors of electricity. Overall, metals are known for their malleability and good conductivity of electricity.
Why does a pineapple conduct electricity?
Biological materials, such as this one, will usually conduct electricity due to ions in the liquid. Since an ion has an electrical charge, and is relatively free to move around, it can conduct an electrical current.
How does the ability to conduct heat differ between metal and nonmetals?
A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals. Cations are usually formed by electron loss.
Why do you think substances that are made up pf molecules do not normally conduct electricity?
Substances made up of molecules do not usually conduct electricity because the electrons in their molecules are tightly bound and not free to move and carry an electric charge. This lack of free-moving charged particles means that the substance cannot conduct electricity like metals or ions.
What type of material conducts electricity?
materials that usually have an extra or unpaired electron in their outermost orbital of its atom conduct electricity
Do materials that conduct heat also tend to conduct electricity?
Usually, yes.
Which elements don't conduct electricity?
there is no element that can't conduct electricity, only elements that do it well and others that don't do it so well. Rubber is a very poor conductor of electricity, while copper, silver and gold are very good conductors.
Does nitrogen conduct electricty?
Not usually. With a sufficiently high voltage, however, nitrogen can be caused to ionize and then can conduct electricity.
Why can ionic compounds conduct electricity but molecular compounds usually can not?
Ionic compounds can conduct electricity because the ions in the solid state can move and carry electric charge. In contrast, molecular compounds usually do not conduct electricity because they do not dissociate into ions in solution or in the solid state, resulting in no free charge carriers to conduct electricity.
Does an iron nail conduct electricity?
Yes they do, they have approximately .3 volts of conductivity.
What elements are not malleable and do not conduct electricity?
Insulators. Their valence electrons are tightly bound because the valence shell is close to full or full. Since each shell can only only hold a certain amount of electrons, the number of electrons depends on which shell is the outer or valence shell.
What elements usually have the ability to be stretched bent and conduct electricity?
The metal elements.

Does silver that has oxidized conduct electricity?
Not especially well. However, the oxidation is usually limited to the surface, so the pure silver "core" will still conduct.
