describe the structure of a metal
Metals are made of a
giant lattice
of
positive
metal ions surrounded by a sea of
delocalised
electrons
What is metallic bonding?
electrostatic
force of attraction between positive
metal ions
Explain why metals are good conductors of heat?
Metals have sea of
delocalised
electrons that carry charge
Why do metals have high melting and boiling
points?
They have strong
electrostatic
force of attraction
they require lots of energy to overcome
Explain why the
alloy
of
copper
and
zinc
is harder than pure copper
Pure coppers are all the same size so layers can slide over each other
In the alloy the atoms are all different sizes so the layers are distorted and they cant slide over each other.
