Electrical Conductivity of Materials - Blue Sea Systems

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).

The Chemistry of Carbon

The electronegativity of carbon (EN = 2.55) is too small to allow carbon to form C 4-ions with most metals and too large for carbon to form C 4+ ions when it reacts with nonmetals. Carbon therefore forms covalent bonds with many other elements. 3. Carbon forms strong double and triple bonds with a nuer of other nonmetals, including N, O, P
