Many metals are "dull grey"; an example is niobium.
Iodine is a non-metal element and appears as a shiny, dark purple solid when in its crystalline form.
a nonmetal because a metal is shiny and strong so a nonmetal is brittle and dull
Sulfur is an element that typically has a dull surface.
You can tell if an element is metal with a hammer by determining if it is malleable (meaning that it can be molded or bent). Just smash it with the hammer, and if it shatters, it probably isn't a metal.
Calcium is a solid, soft dull grey metal at room temperature :)
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.

Metal and nonmetal be simultaneously is not possible.
One homograph for "dull" is "dull." In this context, "dull" can refer to the lack of sharpness or brightness, as in a dull knife or a dull color. "Dull" can also mean lacking interest or excitement, as in a dull movie or a dull conversation.
Leaden is typically a dull gray color, resembling the color of lead metal.
A nonmetal is an element that tends to be dull, brittle, and a poor conductor of heat and electricity.
Iodine is a non-metal element and appears as a shiny, dark purple solid when in its crystalline form.
The colour of a metal pair of zinc and iron can vary. Zinc is a shiny bluish-white metal, while iron is a silvery-grey metal. When zinc and iron are combined in an alloy, such as in galvanized steel, the resulting colour is typically a dull grey or silver color.

Sulfur is an element that typically has a dull surface.
The element that fits this description is sulfur. Sulfur is a non-metal that is brittle, meaning it breaks easily when subjected to stress. It has a dull appearance and does not conduct electricity because it lacks free electrons to carry an electric current.
