SUMMARY
Mercury was classified as a metal in ancient times due to its shiny appearance and heavy weight, despite being a liquid at room temperature. Ancient civilizations, including the Greeks, recognized its metallic surface and mined it from rocks, leading to its categorization as a metal long before the understanding of its position in the periodic table or its electrical conductivity. This classification reflects the observational criteria used by ancient cultures to define metals.
