Students then learn that the periodic table originally grouped elements in columns on the basis of chemical properties, not number of valence electrons.
Consequently, when an atom combines with other atoms, it tends to lose or gain valence electrons to acquire a stable configuration.
It is also possible to identify the chemical state of the elements both from small shifts in the BEe of core electrons and from larger shifts in the BEs of the valence electrons participating in chemical bonding.
2] molecule characterizes a 4-body system due to the independence of the orbitals of the two valence electrons as requested by quantum chemistry, under which conditions no exact solution is possible.
Atomic structure, valence electrons, and covalent bonding
It is also possible to identify the chemical state of the elements both from small shifts in the BEs of core electrons and from larger shifts in the BEs of the valence electrons participating in chemical bonding.
These stable clusters contain eight valence electrons.
The suggested solution originates with the assumption that valence forces are nonlinear (in the wavefunction), non-local, and of non-potential type due to the deep overlapping of the wavepackets of valence electrons in singlet coupling.
