The oxidation state of any lone element is zero.
The oxidation state of a lone element is 0. Lone elements are in their elemental form and do not have any other atoms to share or transfer electrons with, resulting in an oxidation state of 0.
Elements with fixed oxidation numbers include alkali metals (group 1 elements) which have a +1 oxidation state, alkaline earth metals (group 2 elements) which have a +2 oxidation state, and nonmetals in group 17 (halogens) which have a -1 oxidation state in compounds.
The sum of all oxidation states in a neutral molecule or compound is equal to zero. In ions, the sum of all oxidation states is equal to the ion's charge. For atoms in their elemental form, the oxidation state is zero. Specific rules apply to common elements and their typical oxidation states.
The oxidation state of Fe in FeCl3 is +3. Each Cl atom has an oxidation state of -1, and since there are three Cl atoms in FeCl3, the overall charge from the Cl atoms is -3. This makes the Fe atom's oxidation state +3 to balance the charges.
In KNO3, the oxidation state of the carbon atom is +4. In nitrate (NO3-), the overall charge is -1, and the oxygen atoms have an oxidation state of -2. Since there are three oxygen atoms bonded to the carbon atom, the carbon atom must have an oxidation state of +4 to balance out the charges.
zero (0)

In this reaction, the copper ions in copper oxide are reduced to copper atoms, and the hydrogen atoms in elemental hydrogen are oxidized from the zero oxidation state characteristic of all pure elements to the +1 oxidation state of hydrogen atoms bound into water molecules.
The oxidation state of manganese (Mn) in the manganese dimer (Mn₂) is 0, as it is in its elemental form. In this state, the atoms are not combined with any other elements, and therefore, they do not have a positive or negative charge. Each manganese atom in Mn₂ contributes an oxidation state of 0, resulting in a total oxidation state of 0 for the molecule.

all the pure elements have zero oxidation state.....
Fluorine typically has an oxidation state of -1.

They share the same number of electrons (=2) in the valence shell: they have the same oxidation state of +2
Noble gases such as helium, neon, argon, krypton, and xenon exist as single atoms not bonded to other atoms. They are stable with a full outer electron shell, making them unreactive and existing as individual atoms in their natural state.
