Watch the following You Tube video for notes on Metallic bond. ( [Weiner7000 Metallic Bonding and Metallic Properties You Tube Video]). In the video, they do not talk about ductility (ability to draw into smaller diameter wire) but it is the same reasoning as malleable. |

"Ionic bond" - ΔEN > or = 1.7
"Covalent bond - ΔEN < 1.7
The Covalent bond will be discussed in class.
"Ionic bonds" are placed in quotes because this is a misnomer. A bond by definition is a Chemical bond which means that the ve- are being shared. This is not true for Ionic bonds.
Take notes on or print out the following Powerpoint Presentation that explain "Ionic bonds" in more detailed.

The 3rd possible event, Metallic bond, does not depend on ΔEN because all the atoms have low coulombic force (since they are metals) on their valence electrons, so valence electrons can easily be removed from atom to create a "sea of free flowing valence electrons".
