What does the common oxidation number mean?
The common oxidation number means any number that indicates the charge of atoms when an electron is either lost, gained, or shared in a chemical bond. It is known as the ion's number. Also, oxidation numbers in all atoms in a compound must add up to zero.
What is the algebraic sum of the oxidation numbers of the atoms in the formula of a polyatomic ion?
In any neutral compound, this number must be zero.
What is chlorine oxidation number?
It depends on the compound its in. (the range for its oxidation number ranges from -1 to +7 [odd numbers in between are its oxidation numbers exp: -1, +1, +3, +5, +7]) For example if its cl- (only a chlorine ion) then its oxidation number is -1 (simmilar to its valency). If its in the compound NaCl, We know that its total oxidation is 0. (all compunds have an oxidation number of zero) Na has an oxidation number +1. Therefore +1 + x = 0 -> through this you can find the oxidation number of chlorine in this compund. (x representing the oxidation number of chlorine). In this case the answer is x=-1. In the compound HClO4 (perchloric acid), the oxidation number of the total compund is equal to 0. Oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, (+1) + x + (-2*4) = 0 (oxygen in this compund has 4 atoms so -2 multiplied by 4) Thus: +1 + x + (-8) = 0 +1 + x = 8 x= 8 -1 x= +7 So we can see here that the oxidation number of chlorine has become +7. Do the same for any compound that chlorine is involed in. Hope it helps.
What is the oxidation number of element Cr?
As with any other element, the oxidation number of Cr depends on whether and how it is chemically bonded. The oxidation number of pure elements is arbitrarily defined to be 0. In compounds, Cr has oxidation numbers of +2, +3, and +6, depending on the compound.
What is the sum of the oxidation numbers in a molecule?
The sum of oxidation numbers in an uncharged molecule will be 0.For example, H2O has O2- and 2H+.1(-2) + 2(+1)=0The sum of oxidation numbers in a charged species will equal the charge.For example, HCO3- has H+, C4+, and 3O2-.1(+1) + 1(+4) + 3(-2) = -1
Is their any compound of zinc in which zinc have negative oxidation state?
No, there is no such compound
Is there any compound in which fluorine has 1 oxidation state?
HF
What is the oxidation state of iodine in tetrabutylammonium iodide?
The oxidation state of iodine in the compound in the question is -1, as it is in any compound with a name that properly includes the word "iodide" instead of "iodine". "Iodide" is the name of the anion with formula I-1.

Why do you need to know the oxidation number of the elements?
because if you know the oxidation numbers of all the reactants and products in a given reaction, you can determine which, if any, of the reactants were oxidized and which were reduced. oxidized is when the oxidation number increases, reduced is when the oxidation number decreases.
Is there any compound of manganese in negative oxidation state and if exist then formulae?
no, it does not exist

What is an oxidation number and how does an atom get one?
Before involving any chemical reactions or bonds, an atom has an oxidation number of zero. Accepting electrons will lower the oxidation number to negative numbers. Discharging electrons such as metals will result in positive oxidation numbers.
Oxidation numbers for H2PO4-?
In H2PO4-, oxygen has the formal oxidation number -2, phosphorus has the formal oxidation number +5, and hydrogen has the formal oxidation number +1. The formal oxidation numbers for oxygen in almost all oxyanions and for hydrogen in almost all acid anions have these values, so that the remaining element can be assigned a formal oxidation number by the requirement of satisfying the total electrical charge if any shown in the formula.
