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)

Why do oxygen and sulfur have the same oxidation numbers?
Because they have the same number of valence electrons
How many oxidation numbers in each group?
The maximum oxidation number is theoretically equal to the number of valence electrons. For example the oxidation number of chlorine among different compounds can vary from -1 to +7. An exception for this is fluorine, which only have -1 and 0 as its oxidation numbers.
How do valence electrons determine an atoms oxidation number?
what kind of plants live in the rainforest of north america
How many valence electrons is OF2?
Oxidation number of F is -1.Oxidation number of O is +2.
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.

What are the most common oxidation valence number in periodic table?
The most common oxidation numbers are +1 and 2 , - 1 and 2.

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.
The elements what determines how the compound will be formed?
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.
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.
Is the oxidation number of a compound equal to the number of valence electrons it has?
yes it is
Why does chlorine have an oxidation number of 1?
Chlorine has 7 valence electrons and requires one more electron to complete the octet. Hence it has an oxidation number of -1. But, it should be noted that chlorine show positive oxidation numbers (up to +7) also in its compounds
How does knowing lithium's oxidation number help determine what compounds it will form?
The Oxidation number is determined by how many electrons are lost and gained. So, when gaining combining the elements you use the oxidation numbers to predict your compound.
