This is a organic compound. Carbon shows +2 ,+3 and 0 as numbers.
Zero
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.
the charge on a mono-atomic ion is the same as the oxidation number, for a polyatomic ion the charge is the sum of the oxidation numbers of its constituent elements.
The oxidation number of oxygen in most compounds is -2.

The oxidation number determines how much an element is oxidated, so the oxidation number of...1. elements is always 0.2. of simple ions is always the charge, e.g. in Cu2+ the oxidation number of copper is +2.3. hydrogen is usually +1, oxygen usually -2, alkali metals +1, etc.In molecules without a charge, the sum of the oxidation numbers has to be 0. This way you can calculate the oxidation number of its compounds. For example in KMnO4, the oxidation number of oxygen is -2, of K is +1, so if the sum is zero then the oxidation number of Mn has to be +7.In complex ions (OH-, MnO4-, ...) the sum of the oxidation numbers has to be the charge of the ion. (so in OH- and MnO4- it's -1).
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....
I assume you mean the oxidation number of Mn in the permanganate ion , MnO4- The sum of the oxidation numbers is the charge on a polyatomic ion so Mn has an oxidation number of +7 as each O is assigned -2.
The oxidation number is 0. The sum of all oxidation number in a molecule that has not charge is always 0. If it has a charge (ion negative or positive) then the sum must be equal to the charge number.
The sum of oxidation numbers in a neutral compound is always zero. (Note that in order for this to be true, the oxidation number of each type of atom present must by multiplied by the number of such atoms present in the formula unit for the compound before the addition is performed.)
It should always be ZERO.
It must be equal to the charge on the compound/ion
