The number directs the primitive world of imperfect atoms

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

Atoms possess one isolated electron which is weakly linked on the outermost shell and have a strong tendancy of escaping.
These atoms are highly reactive and are rarely found in elemental form in nature.

Hydrogen ( 1 )
Lithium
( 2 +1 )
Sodium
( 2 + 8 + 1 )
Potassium
( 2 + 8 + 8 + 1 )
Rubidium
( 2 + 8 + 18 + 8 + 1 )
caesium, francium...


Alkaline earth metal group

Atoms possess 2 electrons in their outermost shell that they easily give up.

Beryllium ( 2 +2 )
Magnesium
( 2 + 8 + 2)
Calcium
( 2 + 8 + 8 +2 )
Strontium
( 2 + 8 + 18 + 8 +2 )
Barium
( 2 + 8 + 18 + 18 + 8 +2 )
Radium

The triels, earth metal or boron group

Atoms have 3 electrons in their outer energy level.

Boron ( 2 +3 )
Aluminium
( 2 + 8 + 3)
Gallium
( 2 + 8 + 18 + 3 )
Indium, tallium...

The cristallogen group are tetravalent metalloids

Atoms are half-way between the tendancy of giving up 4 electrons or accepting them. They have an elemental crystalline structure.

Carbon ( 2 + 4 )
Silicon
( 2 + 8 + 4 )
Germanium
( 2 + 8 + 18 + 4 )
Tin
( 2 + 8 + 18 +18 + 4 )
Lead
( 2 + 8 + 32 + 18 + 4 )
...

The nitrogen group

Atoms have 5 electrons in their outermost shell. They are therefore 3 electrons short of filling their outermost shell in their non ionized state.

 

Nitrogen ( 2 + 5 )
Phosphorus
( 2 + 8 + 5 )
Arsenic ( 2 + 8 + 18 + 5 )
Antimony (51), bismuth (83)

The chalcogen group

This group has an even stronger tendency of accepting electrons in order to complete their outermost external layer.

Oxygen ( 2 + 6 )
Sulfur
( 2 + 8 + 6 )
Selenium
( 2 + 8 + 18 + 6 )
Tellurium (52) Polonium (84)

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 ( 2 + 7 )
Chlorine
( 2 + 8 + 7 )
Brominates ( 2 + 8 + 18 + 7 )
Iodine
( 2 + 8 + 18 + 18 + 7 )
...

Rare gases have a lack of chemical reactivity

Helium 2
Neon 2+8
Argon 2+8+8
Kripton 2+8+18+8
Xenon 2+8+18+18+8
Radon 2+8+18+32+18+8

Table taken from the encyclopedia "clartés" , the laws of matter, edition 1948 onwords and also from internet Wikipedia.

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")
