Nonmetals are elements that are brittle and dull.
The elements that are brittle are elements that are non-metallic. These include elements like sulfur, oxygen, nitrogen, phosphorus, and hydrogen.
+++
Three in that list are gases so cannot be described as brittle at all! Brittleness is a characteristic only of solid materials.
Any solid non metal has the physical properties of being brittle and being a poor conductor of heat and electricity. An example is sulfur.
Example are: carbon (as graphite), silicon, boron etc.
Nonmetals and some metalloids
carcolosion solids
Solid nonmetals tend to be brittle.
Metalloids
nonmetals
Non metals
Any of the ceramic like materials. Look to the up and to the right of the periodic table. Semi-metals and solid non metals would be good places to start.
Energy
No it is an excellent conductor of heat and electricity
The element that is a good conductor that begins with the letter S is Selenium. Another choice could be Scandium.
Silicon is a poor conductor of heat. So is
A nonmetal is an element that tends to be dull, brittle, and a poor conductor of heat and electricity.
Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity are non metals. A metal is an element that has luster, is a good conductor of heat and electricity, is malleable, and is ductile
metalloid
Both Electricity and Heat are forms of energy. If an element were a poor conductor of both it would simply mean that particular element was a poor conductor of energy.
It is a poor material because it is very brittle. This is caused by its high carbon content. It is a poor material because it is very brittle. This is caused by its high carbon content.

They are shiny!
Yes, it is true.
