A cornerstone for quantum mechanic and entire chemistry is represented
by actual description of chemical bounds.
It is accepted that covalent bonds are formed as a result of the
sharing of one or more electrons between atoms. There is no conceptual
explanation, how the electrons participating at bound are moving
around or between atoms. As usual, quantum mechanic, in its variants,
Valence theory and Orbital Molecular theory, predict a certain
probability for electrons to be in certain region of space, without an
intuitive explanation.
In proposed model, a covalent bound is formed as result of coupling
between electron magnetic moments. No sharing of electrons is allowed,
no increased density of electrons in the space between atoms
participating at bound formation. Quantum mechanic is ruled out and an
analogy with an interaction between two macroscopic magnets can be
made. The interaction between these magnetic moments can explain the
covalent bound formation. Their spatial orientation can explain the
orientation of covalent bounds in space.
The old text about covalent bound is corrected and improved at new

Ionic, coordinative bound and metallic bound are revised in the new
chemistry book, too.
