What mineral holds the highest electrical charge?

When discussing the highest electrical conductivity, it is important to distinguish between the ability of a material to conduct electricity and the concept of holding an "electrical charge."

Electrical Conductivity

The metals that are known for their high electrical conductivity are:

• Silver: It is the most conductive metal, with the highest electrical conductivity due to its single, free-moving valence electrons25.
• Copper: Copper is highly conductive and widely used in electrical wiring due to its excellent conductivity and other beneficial properties25.
• Gold: Gold also has high electrical conductivity, though it is less commonly used for wiring due to its higher cost25.

Electrical Charge in Minerals

If you are referring to minerals that can generate or hold an electrical charge under certain conditions, you might be looking at piezoelectric or pyroelectric materials:

• Quartz (SiO2): Known for its piezoelectric properties, where mechanical stress can generate an electric charge4.
• Tourmaline: This mineral exhibits pyroelectric properties, generating an electric field when heated or cooled4.

However, these minerals do not "hold" electrical charge in the same way conductive metals do; instead, they generate electric charges under specific conditions like mechanical stress or temperature changes.
