Oxidation numbers help determine the correct ratio of elements in a compound. By assigning oxidation numbers to each element, it is possible to balance the charges to show a neutral compound. The sum of the oxidation numbers in a compound should equal zero for a neutral compound or the overall charge for an ion.

Explain why formulas for compounds are never written using oxidation numbers as part of the formula?
Formulas for compounds do not include oxidation numbers because these numbers are specific to an individual atom within a compound, and the compound as a whole remains neutral. Including oxidation numbers in the formula would imply a charge on the compound, which is not accurate for neutral compounds. The formula provides the ratio of atoms in the compound, while oxidation numbers are used to determine how electrons are distributed in a chemical species.
What is a properly written formula for the compound between copper and bromine?
With the oxidation state being II for copper. CuBr2
Where is the oxidation number written?
The oxidation number is typically written as a superscript to the right of the chemical symbol in a chemical formula. It represents the charge that an atom would have if the compound was ionic.
How is a formula of a compound written?
The formula of a compound is written using the symbols of the elements present in the compound and subscript numbers to represent the ratio of each element in the compound. The subscript numbers indicate how many atoms of each element are present in a molecule of the compound.
How are oxidation number determined and used?
This may best be demonstrated by example: Here are two forms (read: oxidation numbers) of iron, as FeO and Fe2O3. Because we know oxygen has a -2 charge per atom, the oxidation number of Fe in FeO is II. As for Fe2O3, we know that the oxidation number of Fe is III; there is no charge on the compound, so the two iron molecules must equally offset the -6 charge from the three oxygen atoms. Oxidation numbers are written as roman numerals. You would write these two forms of iron oxide as iron(II) oxide and iron(III) oxide, respectively. Oxidation states are the (+) or (-) charges written as a superscript.

Yes.
How do you know if a compound word is correctly written?
afterbirth
What do you write to name of a compound written as Cu0?
This is the formula for Copper (II) Oxide Copper has two possible oxidation numbers (+2 or +1) since there are no written subscripts for in the formula CuO, copper's oxidation number must have been +2 (If it had been +1, the formula would be Cu2O and the name of the compound woould be Copper (I) Oxide)

Name given to elements with more than one oxidation number?
The following elements have more than one oxidation number: Mercury, Chromium, Copper, Iron, Tin, and Lead. The ones with different oxidation numbers, also has a sort of name that goes with it. For example, Pb+4's name is actually "Plumbic".
Is the words Thirty one a example of correctly written compound word?
yes but thirty and one have to be stuck together
