We consider some known properties of metals, which are 
explained incompletely by the existing ideas or are contradictory. 
It is shown that the notion of a metallic bond involves three types 
of bonds with different energy regions of action. Based on the experimental 
data obtained at the initial stages of formation of a metallic structure 
from evaporated metals, we have drawn the conclusion on the existence 
of the smallest grains. The introduction of the notion of the deformation 
energy of metals has been substantiated, and formulas for its determination 
have been proposed. The intergranular binding energy has been determined. 
The probable mechanisms of destruction and binding of metals under 
mechanical and thermal actions are discussed.
