What element is very brittle?
osmium (Os), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table and the densest naturally occurring element. A gray-white metal, osmium is very hard, brittle, and difficult to work, even at high temperatures.
What type of element is dull?
Elements like O (oxygen) and H (hydrogen) are members of nonmetals. They can be a solid or a gas at room temperature. They have an appearance that is dull or without luster. Nonmetals are very poor conductors of heat or electric energy.
Is carbon dull and brittle?
Elemental carbon is a black, dull-looking solid that conducts heat and electricity well. It is very brittle and cannot be made into thin sheets or long wires.
Are metals dull and brittle?
Metals are ductile and malleable, so their shape can be easily changed into thin wires or sheets. Metals will corrode, gradually wearing away like rusting iron. Nonmetals, on the right side of the periodic table, are very different from metals. Their surface is dull and they are poor conductor of heat and electricity.
Is Zinc dull and brittle?
Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table. It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110°C and 150°C.
Is sulfur dull and brittle?
Sulfur (chemical symbol: S) Sulfur is a dull-yellow, lustrous, odorless and brittle material that reacts with all elements, except for gold, platinum, iridium, tellurium and the noble gases. In nature, sulfur is often found in sulfide and sulfate mineral deposits and can also exist in its raw elemental form.
Are metals brittle?
Metals are not generally brittle. Rather, they are malleable and ductile.
Which element is dull and brittle at room temperature?
NonmetalsNonmetals are generally either gases or dull and brittle solids at room temperature. They are poor conductors of heat and electricity.

Is carbon shiny or dull?
Answer: Elemental carbon is a black, dull-looking solid that conducts heat and electricity well. It is very brittle and cannot be made into thin sheets or long wires.
Is copper shiny or dull?
Copper is a reddish orange, soft metal that takes on a bright metallic luster. It is malleable, ductile, and an excellent conductor of heat and electricity – only silver has a higher electrical conductivity than copper. Copper surfaces exposed to air gradually tarnish to a dull, brownish color.
Is brittle metal or nonmetal?
Brittleness is the property of being broken easily. Non-metals generally show brittleness.
What type of metals are dull?
Answer and Explanation: Metals that have a dull appearance will be those that are left out to oxidize; those that quickly oxidize and react with the atmosphere will most rapidly appear dull rather than shiny. Metals like lithium, magnesium, and zinc all quickly oxidize.
Is dull a metal or nonmetal?
Properties of nonmetals include: Dull, not shiny. Poor conductor of heat. Poor conductor of electricity.
Is the element carbon shiny or dull?
Elemental carbon is a black, dull-looking solid that conducts heat and electricity well. It is very brittle and cannot be made into thin sheets or long wires. Of these properties, how does carbon behave as a metal?
Are metals dull in appearance?
All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide.
