Sulfur is an element that typically has a dull surface.
a nonmetal because a metal is shiny and strong so a nonmetal is brittle and dull
Slate is typically dull in appearance. It has a matte finish and does not have a shiny or reflective surface.
Brittle materials can exhibit both shiny and dull appearances. Whether a brittle material looks shiny or dull depends on its composition and surface characteristics. Some brittle materials might have a shiny appearance due to a smooth surface finish, while others may appear dull if they have a rough or textured surface.
To dull a shiny painted surface, you can lightly sand it with fine-grit sandpaper to create a matte finish. Alternatively, you can apply a matte or satin topcoat over the shiny surface to reduce its glossiness.
Chlorine, in its elemental form, is a diatomic gas at room temperature and pressure, so it does not have a surface. When chlorine is in a liquid or solid state, it appears as a yellow-greenish liquid or solid, and it does not have a shiny or dull surface.
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.
After my opinion the fresh surface of copper is not dull.
A dull surface is often referred to as matte or flat.
A dull surface is a better absorber of infrared radiation heat compared to a shiny surface. The rough texture of a dull surface allows for more absorption of infrared radiation, while a shiny surface reflects much of the radiation.
a metalloid
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....
One example of an element with a dull surface that is not easily shaped is lead. Lead is a soft and malleable metal with a dull appearance that can be cut with a knife but does not easily hold a shape when molded.

The fresh surface of neptunium is silvery.

It's unlikely to see a clear reflection in a dull surface since it lacks the smoothness needed to reflect light. Instead, the light hitting a dull surface scatters in various directions, resulting in a diffused and distorted reflection.
