Transcript of Metallic Bonding
Metals lose their valence electrons and become cations
“Loose” valence electrons form a “sea of electrons”
Loose electrons are “free to move”
Metal bonds
Strength Malleability Ductility Electrical Conductivity Thermal conductivity Luster
easily bent, pressed or hammered
layers of atoms slide over each other
the electrons can run in between ions when layers are bent
Alnico (AlNiCo)
Brass (CuZn)
Bronze (CuSnAl)
Cast iron (CFe)
Steel (CFe)
Stainless Steel (CFeNiCr)
