Numbers give characterized homologous behaviour to a group. They were the first in the universe to create the identities of matter and the relationship between them. Their properties relate to the relationship with the enlightment of thought that allows the definition of transcendance.
A chemical reaction can be considered as being a sharing or the exchange of electrons between two atoms in the world of imperfect atoms while perfect atoms don't need to react with others.
The
ability of an atom reacting chemically is linked to the non saturation of the
electron outermost shell. This constitutes in dynamic exchanges during which
some of the electrons are borrowed or given up between the atoms. When the external
layer of the atom reaches eight electrons, it becomes saturated resulting in
the configuration of a rare gas.
The number of electrons in the outermost shell determines the
identity and the belonging of an element to a group with a numerical analogy
that gives it similar properties.
Chemists have established 7 families of imperfect atoms :
|
Alkali metal group |
Hydrogen

Beryllium
(

The
triels, earth metal or boron group |
Boron
(

The
cristallogen group are tetravalent metalloids |
Carbon
( 2

The
nitrogen group
|
Nitrogen
(

The chalcogen group |
Oxygen
(

| The
halogen group Atoms are eager to accept only one electron to complete their outermost shell. Owing to their high reactivity, the halogens are found in compounds or as ions. |
Fluorine

This table highlights the reaction ability of an atom linked to the non saturation of its outermost shell which characterises its chemichal exchanges.
In the eighth group, the electronic outermost shell is saturated as it contains eight electrons. This is the series of rare gases that don't have any kind of chemical associations. Here, this group has been designated as the group of perfect atoms. (See chapter "4 states of matter")
