the answer is soooooo simple y r u even on wiki it is a nonmetal
any non-metal such as nitrogen, chlorine, oxygen, iodine, and so forth, usually found towards the right on a Periodic Table (on the right side of the ladder step line)
Tungsten is a metal that is dull and not maleable.
magnesium
Aluminum
Tungsten
This element is a metalloid as it has properties (dull but conducts electrical current) from both metals and non-metals.
These are characteristics of solid nonmetal elements.
It is in fact the best radiator. Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver. While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)
A layer of aluminium oxide is formed on the surface.
The Octopus leaf, originating in the northern Amazon. Surprisingly, they are not flammable, rather broad-shaped and dull.
Element that has a low melting point and a dull surface, breaks easily, is a poor conductor of heat and electricity, and tends to gain electrons in a chemical reaction....
Element that has a low melting point and a dull surface, breaks easily, is a poor conductor of heat and electricity, and tends to gain elestrons in a chemical reaction.
a nonmetal because a metal is shiny and strong so a nonmetal is brittle and dull

After my opinion the fresh surface of copper is not dull.
These are characteristics of solid nonmetal elements.
Many metals are "dull grey"; an example is niobium.
Dull surface is a better absorber. A shiny surface would better reflect than absorb.
matte
a metalloid
A dull surface will absorb infrared best, but it needs to be dull at infrared wavelengths. Do not judge the infrared behavior by the visible performance.
