The sum of oxidation numbers in an uncharged molecule will be 0.
For example, H2O has O2- and 2H+.
1(-2) + 2(+1)=0
The 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
No, they are not same. Oxidation numbers do not have any correlation with oxygen. For example, let's take a compound with no oxygen in it. In NaCl: the oxidation number of sodium ion is +1 where that of chloride ion is -1.
their relationship is quite complex but they do love each other
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
There are two oxidation numbers. P shows +5 oxidation number.
-3. The sum of oxidation numbers of the atoms in all polyatomic ion is the net charge - its part of the definition of oxidation number.
sum will be zero
0.

In a neutral compound, the sum of the oxidation numbers of the atoms in the compound is zero.
-3. The sum of oxidation numbers of the atoms in all polyatomic ion is the net charge - its part of the definition of oxidation number.

Zero
0 they are neutral
0.
The oxidation number of oxygen in most compounds is -2.
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.
It should always be ZERO.
0 because all compounds have an oxidation number of 0. It's the ions (fe S O) that have oxidation numbers, The sum of these oxidation numbers always = 0 in a compound and hence a compound has a oxidation number of 0. :-) hope this helped....
