In metallic bonding, the electrons are surrendered to a common
pool and become shared by all the atoms in the solid metal.
Metallic bonding is found in metals and their alloys.
When the atoms give up their valence electrons, they form ions. These ions
are held together by the electron cloud surrounding them.
These bonds are less strong than ionic or covalent bonds. This gives reasonable
strength and stiffness while allowing the atoms to slide past each other under
high stress, which provides good ductility. The 'cloud' of free electrons is highly
mobile, resulting in good electrical conductivity.
