The oxidation numbers in a neutral compound must equal zero. This is because the overall charge of a neutral compound is zero, so the sum of the oxidation numbers must balance out to zero.
The sum of the oxidation numbers in a neutral compound is equal to zero. This is because in a neutral compound, the total positive oxidation numbers are balanced by the total negative oxidation numbers to give a net charge of zero.
The sum of the oxidation numbers in a compound is zero for a neutral compound. This is because the total positive oxidation numbers from the cations must equal the total negative oxidation numbers from the anions to balance out and form a neutral compound.
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.
The sum of oxidation numbers in a compound is zero for a neutral compound and equal to the charge of the ion for an ionic compound. This rule stems from the fact that the total charge of a compound must be zero for a neutral compound and must balance out for an ionic compound.
The sum of all oxidation numbers in any compound is zero. This is because atoms in a compound are electrically neutral, and the oxidation numbers reflect the charge of the atoms when they gain or lose electrons.
The sum of the oxidation numbers in a neutral compound is equal to zero. This is because in a neutral compound, the total positive oxidation numbers are balanced by the total negative oxidation numbers to give a net charge of zero.

It must be equal to the charge on the compound/ion
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
Positive oxidation numbers are assigned to elements that lose electrons in a compound, while negative oxidation numbers are assigned to elements that gain electrons. The oxidation number is determined by the number of electrons gained or lost in forming the compound. The sum of oxidation numbers in a compound is always zero for a neutral compound, or equal to the charge of the ion in an ionic compound.
The oxidation numbers of each element in HNO3 are: H is +1, N is +5, and O is -2. The sum of the oxidation numbers in a neutral compound like HNO3 must equal zero.
The oxidation number of sulfur in Li2SO4 is +6. This is because the oxidation numbers of Li and O are +1 and -2 respectively, and in a neutral compound the sum of all oxidation numbers must equal zero.
To find the oxidation number for Zn in ZnSO4, you need to consider the oxidation numbers of the other elements. In ZnSO4, oxygen usually has an oxidation number of -2 and sulfur of +6. Since the compound is neutral, the sum of the oxidation numbers of all elements must equal zero. Hence, the oxidation number of Zn in ZnSO4 is +2.
In the compound Co2O3, cobalt's oxidation number is +3. Each oxygen atom has an oxidation number of -2, and since the compound is neutral, the sum of the oxidation numbers must equal zero, leading to cobalt having an oxidation number of +3.
