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
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.
Chemical Properties of Non-Metals
