Which element will never have an oxidation number?
Noble gases, also known as group 18 elements, will never have an oxidation number because they have a full valence shell of electrons, making them very stable and unreactive.
What is the oxidation number for F2?
The oxidation number of F, or Fluorine, is F-1. Since it is in the seventh group on the periodic table, it has seven valence electrons. It needs to get eight valence electrons to be stable, so it will gain one electron.
In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
Why is the oxidation state of fluorine never positive?
An element exhibits a positive oxidation state when it is bonded to a more electronegative element. Fluorine is the most electronegative of all the elements. But what if fluorine bonds with extremely elecronegative oxygen and nitrogen ligands like -OCF3, -OTeF5, -OIO2F2, -N(SO2CF3)2, -N3, -N5(pentazole ligand) etc.? eg: F-OTeF5
In which of the compounds does nitrogen have an oxidation number of -2?
It never has -2 oxidation number. Nitrogen oxidation numbers are possible: -3 (nitrides), 0 (elemental), +3 (nitrites), +5 (nitrates). Also +1, +2 and maybe +4 are possible (in Nitro-oxides only).

Can an electric charge be positive?
When a process of oxidation takes place the element acquires a unit positive charge. The number of protons are more than the number of electrons in an element which gives the element its positive charge as the protons have a positive charge.
Does oxygen ever have a 3- oxidation number?
No, oxygen will never have a -3 oxidation number. If it had a -3 oxidation number, it would not have a full octet. It would have a +1 charge, therefore making it not happy.
Is a number alwayssometimesor never a positive number?
sometimes
Is a number alwayssometimesore never a positive number?
sometimes
When a positive number is the same as in negative number is?
Never.

In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.

Is a negative number bigger than a positive number?
Never.
When can the square of a negative number be negative?
This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.
The absolute value of a number is never?
iT IS NEVER NEGATIVE, IT IS ALWAYS POSITIVE
