All metals
yes alkali metals are suitable for photo electric emission
Metals are good electric conductors.
all metals are good conductors of heat and electric currents
Both of these are metals as well as good electric conductors.
No, most metals are electrical conductors. This means that most metals will conduct an electric current in the presence of an electric field.
Electrons.
Electric current flows in conducting materials such as metals. The best conductor of electric current is silver, followed closely by copper and then aluminium.
Metals that are poor conductors of electricity include tungsten, bismuth, and manganese. These metals have high resistivity due to their electron configuration, which hinders the flow of electric current through them.
Metals are conductive because they have free-moving electrons that can carry electric current easily through the material.
