The oxidation number determines how much an element is oxidated, so the oxidation number of...
1. elements is always 0.
2. of simple ions is always the charge, e.g. in Cu2+ the oxidation number of copper is +2.
3. hydrogen is usually +1, oxygen usually -2, alkali metals +1, etc.
In molecules without a charge, the sum of the oxidation numbers has to be 0. This way you can calculate the oxidation number of its compounds. For example in KMnO4, the oxidation number of oxygen is -2, of K is +1, so if the sum is zero then the oxidation number of Mn has to be +7.
In complex ions (OH-, MnO4-, ...) the sum of the oxidation numbers has to be the charge of the ion. (so in OH- and MnO4- it's -1).
Oxidation state is what determines the number of each atom. This is in the ionic formula.
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.
The oxidation state of an element is determined by the number of electrons the element needs to lose or gain to have a full valence electron shell.
oxidation number of I is -1. oxidation number of F is +1.
The number of electrons of the element needs to lose or gain to have a full valence shell (apex)
