what is the difference between oxidation state and formal charge?
13254
We can obtain oxidation numbers by arbitrarily assigning the electrons of each covalent bond to the more electronegative atom in the bond. This is in contrast to the Formal Charge which divides each bonding pair equally without concern for which atom may be more electronegative.

Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. ... Electrons are electrochemically negatively charged particles that move random around the nucleus. They have a relatively small mass compared to Protons and Neutrons.

Oxygen is more electronegative than sulphur. Hence it is easier for oxides to accept the electron pair of an incoming nucleophile and get reduced than sulphides.

As nouns the difference between oxidation and epoxidation is that oxidation is the combination of a substance with oxygen while epoxidation is (organic chemistry) any reaction that converts a compound (especially an alkene) into an epoxide.

Fractional Values for Oxidation States The oxidation states are usually in whole numbers, but in some cases, they are in fractional numbers. Consider Fe3O4. In most cases, atoms of the same element in a given compound have the same oxidation states, but each atom can have a different state than the other.

The imbalance of protons and electrons now creates a charge of +3 on the atom. Atoms with a charge are known as IONS. More precisely atoms with a positive charge are known as cations while atoms with a negative charge are known as anions. Boron, above, forms a cation.

If an atom loses or gains electrons it develops ionic charge. ... So oxidation number either pertains to the ratio of electrons to protons that an atom possess perhaps in respect to covalent compounds, while ionic charges is used in situations within ionic compounds. .

Chlorine is the only element to have changed oxidation state. However, its transition is more complicated than previously-discussed examples: it is both oxidized and reduced. The NaCl chlorine atom is reduced to a -1 oxidation state; the NaClO chlorine atom is oxidized to a state of +1.

I think it means complete charge for actual charge as in ions while a formal charge is just a partial charge for different atoms in the molecule. Because the electrons are shared, there is no actual positive charge due to an unbalanced electron to proton ratio (as in 7 protons in N while only having 5 electrons).

Valency is the number of electrons present in the outermost shell of a particular element whereas oxidation state is the number of electrons that an element in a particular compound has lost or gained. This is the main difference between valency and oxidation state.

Technically speaking, oxidation is a chemical reaction in which a molecule, atom or ion loses electrons. Oxidation is a half reaction which cannot occur on its own. It must always be accompanied by reduction, which is a chemical reaction in which a molecule, atom or ion gains electrons.

However, since the “number of bonding electrons divided by 2” term is also equal to the number of bonds surrounding the atom, here's the shortcut formula: Formal Charge = [# of valence electrons on atom] – [non-bonded electrons + number of bonds].

An ion carries a charge, that means that the number of electrons and protons do not match. Electrons have a negative charge and protons have a positive charge. A radical has an unpaired electron, but does not have a net charge because the number of protons equals the number of electrons.

Transition Metal Compounds. The bonding in the simple compounds of the transition elements ranges from ionic to covalent. In their lower oxidation states, the transition elements form ionic compounds; in their higher oxidation states, they form covalent compounds or polyatomic ions.

charge is always related to atoms whereas valency is related to elements and is similar to the number of ion (negative or positive) present on the element. VALENCY IS A COMBINING CAPACITY OF AN ELEMENT.

An ion has a non-zero electric charge. A radical has an atom with unfilled electron shells and so is very reactive, but is electrically neutral.

The oxidation state of an atom in a molecule gives the number of valence electrons it has gained or lost. In contrast to the valency number, the oxidation state can be positive (for an electropositive atom) or negative (for an electronegative atom).
