The Crystalline Lattice
vs
Metallic Bonding
Why Metals and Ionic Compounds
are so Different
The Crystalline Lattice
• The Crystalline Lattice of Ionic Bonding
a predictable and regular 3-d arrangement of
_________ and __________ such that
_______________ is minimized and
_______________ is maximized -- leading to a
_________ low ___________ structure called
a crystalline lattice.
Simplest unit is called a _________ _____ not a
___________________.

Metallic Bonding
• An Electron Sea of _________________
____________ electrons are equally ___________
to the stationary __________. These electrons act
as the “________” that holds the metal atoms
together. These mobile electrons also act as a
_____________ or _____________ in the metal,
placing themselves between ______________, thus
disallowing _____________ and ______________.
This explains the __________________ of metals.
This sea of mobile electrons also allows metals to
______________ and to ________ (have ________).
