SEA OF ELECTRONS MODEL
type of metallic bonding (metals form cations)
positively charged metal ions → held together by a delocalized (free-moving) valence electrons SHARED
Metallic bond
the electrostatic attraction between the free-moving electrons, with a negative electrical charge, and the protons in the metal cation.
Valence electrons move freely between the positively charged metal cations.
Why can metals bend w/o breaking
The electrons can rearrange themselves around the positive charges
What do solids have
specific crystal structures (crystal lattice)
Why do metals conduct electricity
because their electrons move freely in them.
Why do metals have VERY high melting points
because of their strong electrostatic forces
Relationship btw charge and melting point
directly promotional (more protons→ stronger attraction→harder bond to break)
