The difference in properties between metal and nonmetal solids (i.e. brittleness, malleability, conduction of both heat and electrical current) is due to availability or absence of free electrons. Contrarily to abundance of free electrons in metals, free electrons are much fewer in nonmetal objects. Electrons that are not bound to atoms are free to roam about, and that is what free electrons do (everywhere) in a piece of metal. These electrons would take impact energy and (practically instantly) distribute it throughout the piece, acting like a bumper in a car. It helps to remember that things are mostly empty space as that is how atoms are.
Atomic properties explain also the difference in heat transfer: metals feel cold on a touch because free electrons immediately take energy from a tip of a finger and 'run away with it.' (We feel something is colder when we give out energy, instead of receiving it.)

What else can I help you with?
Do nonmetals crack?
Yes, in solid form nonmetals tend to be brittle, however, several nonmetals are gasses and one, bromine, is a liquid.
How do solid nonmetals differ from solid metals?
Solid nonmetals typically have lower melting points and boiling points compared to solid metals. Nonmetals tend to be brittle in their solid state, while metals are malleable and ductile. Additionally, nonmetals are usually poor conductors of heat and electricity, whereas metals are good conductors.
Do any nonmetals shatter when struck?
Yes, some nonmetals can shatter when struck, particularly those that are brittle in nature. For example, solid forms of sulfur and phosphorus can break or shatter under impact due to their molecular structures. Unlike metals, which are typically ductile and malleable, brittle nonmetals lack the ability to deform without breaking.
Why do you think that nonmetals are brittle?

What does it mean if something is brittle?
: Separation of a solid accompanied by little or no macroscopic plastic deformation. Typically, brittle fracture occurs by rapid crack propagation with less expenditure of energy than for ductile fracture. :
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.
Do nonmetals crack?
Yes, in solid form nonmetals tend to be brittle, however, several nonmetals are gasses and one, bromine, is a liquid.
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 is an element that is brittle and a poor conductor?
Nonmetals are elements that are brittle and dull.
Is it true that solid nonmetals are brittle?
Yes, solid nonmetals are generally brittle because their atomic and molecular structures make them less able to deform plastically when stressed. This means they are more likely to break or fracture when subjected to mechanical force.
Name two physical properties of nonmetals?
Well, nonmetals are opaque and brittle. They are also bad conductors of heat and electricity.
How are solid nonmetals different from metals?
Solid nonmetals tend to be brittle, have lower melting/boiling points, and are poor conductors of heat and electricity. Metals, on the other hand, are generally malleable, have higher melting/boiling points, and are good conductors of heat and electricity.
How do solid nonmetals differ from solid metals?
Solid nonmetals typically have lower melting points and boiling points compared to solid metals. Nonmetals tend to be brittle in their solid state, while metals are malleable and ductile. Additionally, nonmetals are usually poor conductors of heat and electricity, whereas metals are good conductors.
What are the 5 properties of nonmetals?
They are poor conductors, brittle, not ductile in their solid state, show no metallic luster, and have a low density.
What is tellurium's state at room temperature?
At room temperature, tellurium is a solid. It is a brittle, silvery-white metalloid element that belongs to the group of nonmetals on the periodic table.
What is the state of matter of most nonmetals?
Some are solid (eg carbon) some are gaseous (eg oxygen) and one is liquid (bromine).
Do any nonmetals shatter when struck?
Yes, some nonmetals can shatter when struck, particularly those that are brittle in nature. For example, solid forms of sulfur and phosphorus can break or shatter under impact due to their molecular structures. Unlike metals, which are typically ductile and malleable, brittle nonmetals lack the ability to deform without breaking.
