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 nonmetals in the solid state are poor conductors of heat tend to?

It would be nonmetals.


What physical and chemical properties are found among the nonmetals?

Most nonmetals are poor conductions of electricity and heat and are reactive with other elements. Solid nonmetals are dull and brittle.

Elements that are usually dull in appearance and poor conductors of heat and electricity?

There are 17 nonmetals in the periodic table, and they are characterized by four major physical properties. 1. They rarely have metallic luster. 2. They are usually gases at room temperature. 3. Nonmetallic solids are neither malleable nor ductile. 4. They are poor conductors of heat and electricity.
