Native metals were prehistoric man's only access to metal, since the process of extracting metals from their ores is thought to have been discovered around 6500 BC. However, native metals could be found only in impractically small amounts, so while copper and iron were known well before the Copper Age and Iron Age , they did not have a large ...
Many metals are found in uncombined metallic form, in varying degrees of purity. These "metals found as metals" are referred to as native metals, which are a subset of native element minerals. The most well-known native metals are native copper and gold. Nonreactive noble metals usually occur in nature as native metals.

This is a list of 194 sources that list elements classified as metalloids. The sources are listed in chronological order. Lists of metalloids differ since there is no rigorous widely accepted definition of metalloid (or its occasional alias, 'semi-metal'). Individual lists share common ground, with variations occurring at the margins.
