Structures and properties of metallic bonds
- Metals can be bent (ductile)
and can be stretched (malleable) because the layers of atoms in metals slide
over each other when force is applied but will not break due to attractive
force between electrons and metal ions.
- Metals conduct electricity
as it has free electrons which carry current.
- Metals conduct heat as it
has free electrons which gains energy when heated and moves faster to collide
with metal atoms, releasing heat in collisions.
- Metals have high melting and
boiling points because the bonds between metals are very strong. Hence very
high heat energy needed to break the bonds.
