There are no free moving electrons in non metalic compounds. Do when light shines on them the energy simply gets bounced between the atoms.

What are properties for nonmetals?
Nonmetals are very dull looking and are easily broken compared to a normal piece of metal. Nonmetals have high ionization energies and electro negativities. They are generally poor conductors of heat and electricity.Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily. Nonmetals display a wide range of chemical properties and reactivities.
How valence electrons can atoms of nonmetals have?
always more than 4
Do nonmetals have always higher electron affinity than metals?
That is the trend of the periodic table. From left ( where the metals are ) to the right upper corner ( where the most electronegative nonmetals are )
When nonmetals react with other nonmetals the atoms of nonmetals do what with electrons?
Share
Do nonmetals only combine with nonmetals?
No. Nonmetals will also combine with metals and metalloids
Do nonmetals look shiny?
No. Nonmetals are dull, not lustrous.
What are elements that appear dull?
nonmetals
Are physical properties of nonmetals shiny?
Nonmetals are generally not shiny. They tend to be dull.
Minerals that are generally dull not malleable and not ductile and cannot conduct electricity are?
nonmetals
What physical and chemical properties are among the nonmetals?
Most nonmetals are poor conductions of electricity and heat and are reactive with other elements. Solid nonmetals are dull and brittle.
What are two characteristics of nonmetals on the periodic table?
They are bad conductors, and they are dull.
What distinguishes nonmetals from metals?
metals are shiny and good conductors of heat and electricity. Nonmetals are dull and poor conductors of heat and electricity.
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.
Minerals that are generally dull not malleable and not ductile and cannot conduct electricity are .?
Nonmetals
What are three general characteristics if nonmetals?
Nonmetals are generally the opposite of metals. They are very brittle, are not good conductors of heat and electricity, and are dull. Most nonmetals are gases at room temperature, which means they have low boiling points. They have lower densities than nonmetals.
What are nonmetals?
Non-metals are dull, brittle elements that do not conduct electricity.
What is a type of element whose physical properties are generally opposite those of metals?
These are called nonmetals (e.g. carbon, phosphorus, sulfur)Metals (such as gold, titanium, and cobalt) are generally lustrous, malleable, and can conduct electricity. Nonmetals are dull, extremely brittle, and are usually (but not always) non-conductive.
