Which Metals Conduct Electricity? While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring since the days of the telegraph.
Brass is a generic term for a range copper/ zinc alloys. There are many copper zinc alloys , with copper content from 15 % Zn, known as red brass, to 40% zinc , a yellow brass. Copper alloys with zinc content lower than 15 % , although a type of b...
How well does bronze conduct electricity? It is a moderately good conductor, but not great. If you rate pure copper at 100%, then regular annealed copper wire rates an 85%, various aluminum alloys ...
Brass does conduct electricity, but it is not a very good conductor. Not all metals conduct electricity to the same extent. Brass has a low electrical conductivity of only 28 percent, compared to metals such as silver and copper that have almost perfect electrical conductivity.
Salt water is a pretty good conductor of electricity. Its not as good as a metal but still is far from being an insulator. Pure water does not conduct electricity well at all.
Why Do Metals Conduct Electricity? Metals conduct electricity well due to the fact that the outermost electrons in their atoms are held by weak atomic forces, allowing these electrons to flow easily from one atom to another. This flow of electrons is what lies at the heart of an electric current.
They conduct electricity when dissolved in water. I think you are referring to alkaline and alkaline earth metals, which seem to dissolve in water - actually they are not dissolving in the way that ionic substances dissolve, but they are reacting with water to form soluble substances.

electrons are held by the individual ions, so they are not free to conduct electricity. The ions split when dissolved in water and can then carry charge (meaning it can conduct electricity). (d) Bronze (CuZn(s)) [will/will not] conduct electricity on its own. It [will/will not] dissolve in water.
This does not mean that copper has no resistance (is 100% conductive in an absolute sense), but rather that it is the standard by which other materials are measured. The higher the % IACS, the more conductive the material is. This standard refers to a pure, "standard" copper having a resistivity of 1.7241 microhm-cm at 20°C (68°F).
In addition to impurities, other factors that can affect how a metal conducts electricity include frequency, eletctromagnetic fields, and temperature. Silver has the highest conductivity of all metals, but it also has a hefty price tag and it can tarnish, rendering the surface less conductive.
