It indicates how many electrons are required to complete a full valence shell.
In an atom of an element has one or two valence electrons and is not a helium atom, the most likely oxidation state is positive by the number of valence electrons, while if the atom of an element has seven or six electrons, the most likely oxidation state is negative by the number of electrons required to total eight valence electrons. Helium and all the atoms with eight valence electrons have a most likely oxidation state of zero, corresponding to no reaction.

Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
Valence electrons are responsible for chemical boding.

Five valence electrons. They all exhibit different oxidation numbers too!!!!
Oxidation number of F is -1.Oxidation number of O is +2.

Because they have one valence electrons, and if they lose this electron they attain an oxidation number of +1
How many valence electrons do transition elements have?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
Argon's valence number is 8, it has 18 electrons, and its oxidation number is 0 because it doesn't react.

The way in which elements bond to form compounds depends on the arrangement and number of electrons in the atoms. This is what will determine the type of boding that elements will form.
