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.
a nonmetal because a metal is shiny and strong so a nonmetal is brittle and dull
Arsenic is shiny,gray,brittle metallic looking solid.The dull coating is made of arsenic oxides.
Potassium is a soft metal, not brittle. When freshly cut, it has a shiny appearance but quickly oxidizes in air to form a dull oxide coating.
Non-metals are dull (or they are not shiny as metals).

Metals are associated with being shiny and good conductors of electricity. They are typically not dull, brittle, or poor conductors of electricity.
Helium is neither shiny nor dull; it is translucent (transparent; colorless). Helium is a colorless gas

Elements that are brittle and dull are likely to be nonmetals. Nonmetals tend to have brittle, dull properties compared to metals which are typically malleable and lustrous. Examples of brittle and dull elements include carbon in the form of graphite and sulfur.
