oxidation number is defined as a positive or negative number corresponding to the charge that an atom in a molecule or ion would have if the electron pairs belonged entirely to the more electronegative atom.
in this case, they're talking about 'valance electrons'. An example would be...fluorine has 7 valance electrons. when bonded with another element, it would in almost all of the cases want to gain 1 more electron to have a full valance shell of 8 electrons. Therefore, it would become F -1
As a result, fluorine's oxidation number becomes -1, the same as its CHARGE when bonded to ANOTHER element (NOT ITSELF)
when fluorine bonds to itself to become Fluorine gas, its oxidation number is zero. that goes for all ....elements which bond with itself to form a diatomic molecule (oxygen gas, hydrogen gas, etc)

What is the relationship of valence electron and oxidation number?
The valence electrons of an atom determine its ability to form bonds and participate in chemical reactions. The oxidation number of an atom indicates the number of electrons it has gained, lost, or shared in a chemical compound. The valence electrons of an atom can help determine its oxidation number by considering how many electrons the atom needs to reach a stable configuration.
How does oxidation numbers determine the number of atoms?
Oxidation numbers indicate the charge of an atom in a compound. By comparing the oxidation numbers of different atoms in a compound and knowing their charges, you can determine the number of atoms involved in the reaction or compound. These numbers help balance chemical equations and determine the stoichiometry of a reaction.
Is the oxidation number of a compound equal to the number of valence electrons it has?
Not necessarily. The oxidation number of an atom is the charge it would have if all shared electrons were assigned to the more electronegative atom. The number of valence electrons an atom has helps determine its possible oxidation states, but it may not always correspond directly to the oxidation number in a compound.
What rules are used to assign oxidation number?
First, determine which family it is in on the periodic table. The group number equals the number of valence electrons that it has. It needs to end up with eight valence electrons to have a full octet. So if it has seven valence electrons, it will gain one electron to be stable. On the other end of the table, it will lose electrons to be stable.
How do you find highest oxidation number?
For most elements, their highest attainable oxidation number is equal to the number of valence electrons. Examples are the maximum oxidation numbers for: sulfur is +6, phosphorus is +5 and chlorine is +7. Fluorine is an exception which bears oxidation numbers 0, -1/2 and -1.

How do valence electrons determine an atoms oxidation number?
Valence electrons determine an atom's oxidation number by influencing how easily the atom can lose or gain electrons to achieve a stable electron configuration. The oxidation number of an atom is often determined by the number of electrons it loses, gains, or shares when forming chemical bonds with other atoms. Valence electrons play a key role in this process, as they are involved in the bonding interactions that lead to oxidation number changes.
How can one determine the oxidation number of an element in a chemical compound?
To determine the oxidation number of an element in a chemical compound, you need to follow these steps: Identify the element in the compound. Determine the common oxidation states for that element. Assign the oxidation number based on the compound's overall charge and known rules for assigning oxidation numbers. By following these steps, you can accurately determine the oxidation number of an element in a chemical compound.
What is argon valence number and electrons and oxidation number?
Argon's valence number is 8, it has 18 electrons, and its oxidation number is 0 because it doesn't react.
What is the oxidation number of carbon in hcho?
The oxidation number of carbon in formaldehyde (HCHO) is +2. In this molecule, oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. By applying the rules for assigning oxidation numbers in a compound, we can determine that carbon has an oxidation number of +2.
What is the oxidation number for CrPO4?
The oxidation number for Cr in CrPO4 is +3. This is because the overall charge of the compound is neutral, and the oxidation numbers for oxygen (-2) and phosphorus (+5) are known. By calculation, we determine the oxidation number of Cr to be +3.
How is charge related to oxidation number?
Charge refers to the electrical charge of an ion, which is the number of valence electrons gained or lost by an atom. Oxidation number, on the other hand, is a hypothetical charge assigned to an atom in a compound based on a set of rules. The oxidation number can be used to determine the charge of an ion in a compound, but it does not always represent the true charge of the atom.
Why do you need to know the oxidation number of the elements?
because if you know the oxidation numbers of all the reactants and products in a given reaction, you can determine which, if any, of the reactants were oxidized and which were reduced. oxidized is when the oxidation number increases, reduced is when the oxidation number decreases.
