1. Structure and Properties of Metallic Bonds

2. + + + + + + + + + + + + Metallic Bonds
Free-floating – Valence electrons do not stay around any one atom as metals hold them very weakly, instead the cations float in a sea of electrons.
Malleable – hammered into shape, and
Ductile draw into wire are both related to this as the free floating electrons allow the cations to slide past like ball bearings in oil. + + + + + + + + + + + +

4. Metallic Bonds
Conductivity – Metals are very conductive, this is due to the sea of electrons. As the electrons are not attached to a cation in particular, they can move back an forth with great ease leading to the high coductivity.

5. Metallic Bonds
Alloy – mixture of 2 or more elements of which at least 1 is a metal created by mixing the melted ingredients together and allowing to cool. Often have properties superior to the pure elements.
