Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current.A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ ().

Gold Conductivity. While gold is a good electric conductor, and doesn’t tarnish when exposed to the air, it is too expensive for common use. Individual properties make it ideal for specific purposes. Aluminum Conductivity. Aluminum can conduct electricity but it does not conduct electricity as well as copper.

The structure of metals explains their high melting and boiling points and their conductivity. The properties of a metal can be modified by mixing it with another substance to form an alloy.

· Hardness: describes a material's ability to resist scratching. Diamonds have high hardness. Graphite has low hardness. · Brittleness: describes a substance's tendency to shatter.
