Metals

Physical Properties of Metals

Have Luster -shiny Are Conductors -heat and electricity

move through them easily Malleable – Can be hammered into a

different shape Ductile – Can be drawn into a wire High Density – Heavy for their size Metals are solid, except for mercury

Examples of Metal

Physical Properties of NonMetals

Dull – not shiny Nonconductors – heat and electricity do

not move through easily Brittle – break easily Most nonmetals are gases at room

temperature

Examples of NonMetals

Properties of Metals

Metals have luster. This means they are shiny

Properties of Metals

Ductilemetals can be drawn into wire.

Properties of Metals

Malleablemetals can be hammered into sheets

Properties of Metals

Metals have a high melting point. They are also very dense.

Properties of Metals

Conductors Metals are

good conductors of electricity and heat

Properties of Metals

A chemical property of metal is its reaction with water and oxygen. This results in corrosion and rust.

Nonmetals

Properties of Nonmetals

Nonmetals do not have luster; they are dull.

Properties of Nonmetals

BrittleNonmetals are

brittle so they break easily. This means nonmetals ARE NOT ductile or malleable.

Properties of Nonmetals

Nonmetals have low density.

Properties of Nonmetals

They also have a low melting point. This is why they are poor conductors of heat and electricity.

Chemical Properties of Metals Most metals

have 3 or less valence electrons and therefore are likely to lose these electrons in chemical bonds.

Nonmetals have 5 or more valence electrons and therefore usually gain electrons in chemical bonds.
