What are the physical properties of metal and non-metal?
metal- shiny non-metal- dull
What do all non metals have in common?
They are either Solid, Liquid or Gas. They are dull (not lustrous), poor conductors, non malleable, and not ductile
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.
What physical property that is brittle and dull?
Dullness is a physical property.
How do you tell if something is non metal?
go to Ask Jeeves dat doesn't help i need it for gcse
Are insulators dull brittle and poor conductors?
Insulators are conductors
Elements that are brittle and dull are?
cake and ice cream
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.
What are nonmetals?
Non-metals are dull, brittle elements that do not conduct electricity.
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.
What are some elements that are dull and are poor conductors of heat and electricity?
anything that is not of metal or liquified
Is an element that is brittle and dull?
a nonmetal because a metal is shiny and strong so a nonmetal is brittle and dull
What properties do all nonmetals have in common?
Non-metals generally are not good conductors of heat or electricity, have a dull surface, are brittle to the touch, and are not easily molded into shapes.
What are the properties that define an element as a non-metal?
- many nonmetals are gaseous or liquids- densities are not high- hardness of solid elements is not high- nonmetals form frequently anions- nonmetals form frequently compounds with covalent bonds
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 the physical properties of metal and non-metal?
metal- shiny non-metal- dull
Is non-metal dull?
Non-metals are dull (or they are not shiny as metals).
