6 U2 - 6(A) compare metals, nonmetals, and metalloids using physical properties such as

luster, conductivity, or malleability;

atom

Smallest particle of an element.

Element Brittle

color

A pure substance made of only one kind of atom

A physical property; tendency to break, snap, or crack without first bending or changing shape as a result of application of little force; an example is glass, which shatters easily.

Flammable

When a substance will burn instead of melt

Conductor DUCTILE

A substance that allows the flow of electric charge or transfers thermal energy through matter.

A term used to describe a material that can pulled into a long wire.

What does ductile mean?

Drawn into thin wires

electrical conductivity

Luster

The ability to conduct electricty. Wood is a poor conductor.

A physical property; the way the surface of a substance shines or reflects light; most general classification is between metallic (shiny) and

hardness

Insulator Malleability

melting point

Brittle

nonmetallic (dull or glassy). ability of matter to resist scratching

A substance that resists electric current, or a material that resists the flow of heat.

A physical property; able to be shaped or formed into thin sheets by hammering or pressure.

The temperature at which a substance changes from solid to liquid

Non metals tend to be brittle

reactivity solubility

SONOROUS

The tendency of a substance to combine with other elements and create new compounds

The ability of a substance to be dissolved in another substance

Metals are able to produce a ringing sound.

?

state

texture

The smoothness or roughness of a substance.

thermal conductivity

Ability to conduct heat

viscosity Weight

How thick or resistant to flow a fluid is. Molasses is very viscous while water is not.

Physical Property

Metal metals

elements found on the left and center of the periodic table; usually solid, are shiny, conduct electricity, malleable

Located to the left of the zig-zag line. Are malleable, good conductors, ductile, shiny, and mostly solids.

Exception: Hydrogen! It's a nonmetal on the left
