It seems like the answer options are missing from your query. A characteristic that is NOT typical of metals is dullness; metals are typically lustrous and shiny, so dullness would be the opposite. Other characteristics that are NOT typical of metals include:Brittleness:Metals are usually malleable and ductile, meaning they can be shaped and drawn into wires without breaking. Brittleness is more characteristic of non-metals.High melting points (relative to non-metals):While some metals have high melting points, this is not a defining characteristic for all metals. Many non-metals have much lower melting points.Being electronegative:Metals tend to be electropositive (losing electrons easily) rather than electronegative (gaining electrons).Low density:Metals generally have higher densities compared to non-metals. Key characteristics of metals:Lustrous: They have a shiny appearance.Malleable: They can be hammered into thin sheets.Ductile: They can be drawn into wires.Good conductors of heat and electricity: Metals transfer heat and electricity efficiently.
