Fluorine Oxidation Number

  



Fluorine is the most electronegative atom in the entire Periodic Table, so it always gets assigned the other electron in the covalent bond of #H-F# to give #stackrel(-I)F# and #stackrel(+I)H#. What are the oxidation numbers of oxygen and fluorine in the (real) molecule, #OF2#? Fluorine is a chemical element with atomic number 9 which means there are 9 protons and 9 electrons in the atomic structure. The chemical symbol for Fluorine is F. Electron Configuration and Oxidation States of Fluorine. Electron configuration of Fluorine is He 2s2 2p5. Possible oxidation states are -1. Electron Configuration. Atomic Number – Protons, Electrons and Neutrons in Fluorine. Fluorine is a chemical element with atomic number 9 which means there are 9 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.

Red-ox reactions

Fluorine’s oxidation number is always negative. The most electronegative b. The oxidation numbers of alkali metals are always positive. The least electronegative c. Elements such as P, N, and S have positive oxidation numbers in some compounds but have negative oxidation numbers in others. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component.

Red-ox is short for oxidation reduction reaction. The two always go together. It is not possible to have a reduction reaction without an oxidation reaction.

A red-ox reaction is a reaction in which the oxidation states of some of the atoms change.

Oxidation number is a formalized way of keeping track of oxidation state.

When molecules and ionic compounds form electrons are rarely shared equally.

e.g. CF4 is held together by covalent bonds. Even though the electrons are shared, the electrons are not shared equally. Fluorine attracts electrons more strongly than Carbon, so the electrons spend more time near the Fluorine. Chemists have invented an accounting method to keep track of the electrons.

The atom that more strongly attracts the electron is 'given ' the electron.

in CF4 the oxidation number of the

C is +4

the oxidation number of each of the

F's is -1.
Fluorine Oxidation Number
Here are the rules for determining the oxidation number of an atom.

Elements: (including all allotropes) have an oxidation number = 0.

In an ionic compound

Monoatomic ions: oxidation number is the same as charge.

i.e.

Group 1 elements: always have a +1 oxidation number.

Group 2 elements: always have a +2 oxidation number.

When occurring in a molecule (other than an allotropic form of the element)

H always has a +1 oxidation number.

F always has a -1 oxidation number.

O always has a -2 oxidation number, except when bonded to a F or another O in a molecule.

Cl has a -1 oxidation number, except when bonded to a F or an O.

Br has a -1 oxidation number, except when bonded to a F, a Cl, or an O.

I has a -1 oxidation number, except when bonded to a F, a Cl, a Br, or an O.

S has a sometimes has a -2 oxidation number, except when bonded to a F, a Cl, a Br, or an O.

What we are really saying is that the oxidation number of an atom will be the same as the charge on the ion that the element forms so long as the atom is not bonded to a more electronegative element.

For a neutral compound : the sum of the oxidation states must be O.
For a polyatomic ion : the sum of the oxidation states must equal the charge of the ion.

Red-ox reactions are characterized by a transfer of electrons from one atom to another, and thus a change in the oxidation state of the atoms.

The obvious reaction:

Is this a red-ox reaction?

Check the oxidation numbers.
If the oxidation number of any of the elements have changed then a red-ox reaction has occurred

The oxidation number of Na has gone from 0 to +1.
The oxidation number of Cl has gone from 0 to -1.

Yes, this is a red-ox reaction.

One electron was transferred from a Na (if you say 'sodium' you do not need an 'an'..a sodium atom) atom to a Cl atom.

In total, two electrons are transferred each time a molecule of Cl2 is consumed.

Since, the Cl atoms are gaining electrons their charge is being reduced, or made more negative.

This means that the sodium metal is being oxidized, the sodium is losing electrons.

Personally, I remember the first statement gaining electrons charge reduces or makes the oxidation state more negative.

Another fairly obvious reaction:

Yes, this is a redox reaction.

I use the word obvious because the reactants were neutral elements, and the products were ionic compounds. It is pretty clear that electrons have moved; the Na lost an electron to become Na+.

Less obvious, but similar to rusting..combustion:

Are combustion reactions red-ox reactions?

Determine oxidation numbers..

The reactants

H is always +1 so,

O2 is 0

The products

So, C is oxidized. The C atom looses 8 e-'s as it goes from -4 to +4.

The oxidation number of the H atoms does not change.

The O atoms are reduced. Each O atom gains 2 e-'s as each one goes from 0 to -2. The charge is reduced from 0 to -2.

This is an important revelation. Typically, methane is burned, the heat which is produced during the combustion reaction is converted to mechanical energy, and the mechanical energy is converted to electrical energy. However, combustion is just a reaction that moves 8 e-'s from a C atom to 4 O atoms. If the e-'s can be siphoned off the chemical energy can be converted to electrical energy directly. In fact, this is the basis for fuel cells.

NASA uses the reaction of H2 with O2 for two forms of energy.

The main engines of the shuttle burn H2 in pure O2 the heat from the reaction produces rapidly expanding gases and thrust.
The shuttle produces electricity using fuel cells that convert the chemical energy of H2 and O2 directly to electrical energy.

Cars which convert gasoline to electrical energy using fuel cells are being developed. The electrical energy powers electrical motors. Fuel cells would eliminate some of the problems associated with battery powered electrical cars; limited range and long recharge times. while also elimination some of the problems with internal combustion engines. Fuel cells have advantages over internal combustion engines; the fuel cells produce fewer biproducts-carbon monoxide, hydrocarbons, nitrogen dioxide, sulfur dioxide-and fuel cells are more efficient than combustion engines.
