$Cu, Ag$ and $Au$

Vedclass · Answer

(A) Good conductors of electricity are materials that allow electric current to flow through them easily due to the presence of free electrons. Metals like $Cu$ (Copper),$Ag$ (Silver),and $Au$ (Gold) have a large number of free electrons in their metallic lattice,making them excellent conductors. $Si$ (Silicon) and $Ge$ (Germanium) are semiconductors. $Diamond$ is an insulator. $NaCl$ (Sodium Chloride) is an ionic solid that conducts electricity only in a molten state or aqueous solution,not in its solid state. Therefore,the set containing $Cu, Ag$,and $Au$ consists entirely of good conductors.

Identify the set in which all the three materials are good conductors of electricity.
