Nonmetals are the class of elements that are typically brittle and poor conductors of heat. They tend to lack the malleability and ductility found in metals and often exist in solid, liquid, or gaseous states at room temperature. Examples of nonmetals include sulfur, phosphorus, and chlorine. Their properties make them essential in various chemical reactions and applications.

Which type of elements are often dull brittle and poor conductors?
Nonmetals are often dull, brittle, and poor conductors of heat and electricity. Unlike metals, which are typically shiny and malleable, nonmetals tend to have a dull appearance and can break easily when subjected to stress. Common examples of nonmetals include sulfur, phosphorus, and carbon in certain forms.
What are the three main classifications of elements on the periodic table of element?
The three main classifications of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, good conductors of heat and electricity, and malleable. Nonmetals are usually dull in appearance, poor conductors of heat and electricity, and brittle. Metalloids have properties that are intermediate between metals and nonmetals.
What are the names of the major categories of elements on the periodic table?
The major categories of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are usually not shiny, brittle, and poor conductors. Metalloids share properties of both metals and nonmetals.
What do metals and non metals have in common?
Metals and nonmetals are both elements on the periodic table. Metals tend to be shiny, ductile, and good conductors of heat and electricity, while nonmetals are often dull, brittle, and poor conductors. Both types of elements play crucial roles in the properties and reactivity of materials.
What are the physical properties of metal and non-metal?
metal- shiny non-metal- dull
What is the class classification system for Elements?
Elements are classified into classes based on their properties and characteristics. The main classes of elements are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are typically dull, brittle, and poor conductors. Metalloids have properties of both metals and nonmetals.
A characteristic of most nonmetallic solids is that they are?
they are NOT good conductors of heat and they are brittle solids.
What is the largest class of elements?
The largest class of elements on the periodic table is the metals, which make up the majority of the elements. These elements are typically shiny, malleable, and good conductors of heat and electricity.
What are two major categories of elements split into?
The two major categories of elements are metals and nonmetals. Metals are typically shiny, malleable, and good conductors of heat and electricity, while nonmetals are usually dull in appearance, brittle, and poor conductors.
Cu metal non metal?
Copper (Cu) is a metal. Metals are elements that are typically shiny, malleable, and good conductors of heat and electricity. Non-metals, on the other hand, are elements that are generally not shiny, brittle, and poor conductors of heat and electricity.
What is the difference between a metal a nonmetal and a matalloids?
Metals are elements that are shiny, good conductors of heat and electricity, malleable, and ductile. Nonmetals are elements that are poor conductors of heat and electricity and are brittle in solid form. Metalloids have properties that are intermediate between metals and nonmetals and can exhibit characteristics of both.
What are elements that are very brittle and have no metallic luster called?
Elements that are very brittle and have no metallic luster are typically classified as nonmetals. Examples include sulfur, phosphorus, and carbon (in the form of graphite). These elements tend to be poor conductors of heat and electricity.
What nonmetals in the solid state are poor conductors of heat tend to?
Nonmetals in the solid state tend to be brittle and poor conductors of heat.
What class of element listed on the periodic table contain elements that are poor conductors of heat and electric current?
It would be nonmetals.
What are metals and non-metals and metaloids?
Metals are elements that are usually malleable, ductile, conductive of heat and electricty, and lusterous. Non metals are elements that do not exhibit these characteristics. Metaloids are elements with intermediate properties.
Which type of elements are often dull brittle and poor conductors?
Nonmetals are often dull, brittle, and poor conductors of heat and electricity. Unlike metals, which are typically shiny and malleable, nonmetals tend to have a dull appearance and can break easily when subjected to stress. Common examples of nonmetals include sulfur, phosphorus, and carbon in certain forms.
What are 3 major categories of elements?
The three major categories of elements are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are generally brittle, dull, and poor conductors. Metalloids have characteristics of both metals and nonmetals.
