A metal (e.g. gold, silver, or platinum) that resists chemical action, does not corrode, and is not easily attacked by acids.
Metal characterized by a lack of chemical activity with atmosphere and mild acids, such as gold, silver, and platinum. Since noble metals are non-reactive, they do not develop rust (corrosion) and therefore have indefinite life span.
