The definition of a metal includes the fact that it is shiny when freshly cut. Metals that readily oxidise would therefore have a dull appearance as a layer of that metal's oxide would quickly form on the outside. Such metals include Zinc, Magnesium and Lead.
Any metal that has been left to oxidise for a long time would be dull, so copper or even silver, for example, could also be dull.
Unreactive metals are rarely ever dull. Thus Gold and Platinum are examples of metals that are almost never dull.
metals are malleable in nature
The element is most likely a metal, as metals tend to have good electrical conductivity. The description of a black, dull surface suggests that the metal may not be very shiny or reflective, giving it a dull appearance.
dull and or plain
Metals are associated with being shiny and good conductors of electricity. They are typically not dull, brittle, or poor conductors of electricity.
Dull is not a substance but rather an adjective describing the appearance of an object. However, in the context of materials, metals typically have a shiny luster, whereas nonmetals can often appear dull. Therefore, if something is described as dull, it is more likely to be a nonmetal.
dull metals are dull obviously but other than that no

By there shape, most of them have a shiny look to them, however some are dull.
The element is most likely a metal, as metals tend to have good electrical conductivity. The description of a black, dull surface suggests that the metal may not be very shiny or reflective, giving it a dull appearance.
Non-metals are dull (or they are not shiny as metals).
Most older metals will be somewhat dull from wear or corrosion- but new metals can be aged to make them look older.
My opinion would be metal. Since non metals are brittle and dull, I disagree with the non-metals.

There are a number of physical properties that can be present in meted metals. These metals are often very dull in appearance for example.
