When the binding of metals, follows the trend of each atom, its valence to, and controls this at a joint called electron gas in the remaining positively charged atomic hulls together. This is a large number of easily moving cargo carriers are available, giving the high conductivity of the metal results.

Described by all bond types can ultimately macroscopic solid structure, in which the atoms over large length scales very regularly in periodic lattice structures. This fact is very important to understanding the behavior of solids (solid-state physics basis of quantum mechanics).
