Properties of Metals.
The free electrons in metals
1) hold the structure together as
if the metal ions were in a
"glue".
Delocalised
electrons hold the ions together by strong electrostatic forces.
2) cause metals to conduct heat and electricity.
3) allow the metal ions to
slide over each other.
Metals are malleable which means they are soft, easily bent and
shaped
and can be pressed or beaten
into thin sheets.
Metals are ductile which means that they can be drawn down into wires.
The properties of a metal can be changed
by mixing in other elements to make an
alloy.
Metals have high
melting and boiling points.
They are all solid at room temperature
except mercury, which is liquid.
