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 is eual to zero.Neutral atoms are pure form.
This is a neutral compound. Oxidation number of it is +2.
This is a neutral compound. Na shows the +1 OXIDATION NUMBER.
Sodium is always 1+, oxygen in this case is 2-. The sum of all of these atoms' oxidation numbers is -4. Therefore, since the compound in neutral carbon must have a +4 oxidation number.
It should always be ZERO.

For a neutral atom or compound, the oxidation number is always 0. For an ion, the overall oxidation number is its charge. If you need to find an oxidation number to a particular atom of a compound, there are two ways: working out the Lewis structures or balancing the charges.

The oxidation number of oxygen in most compounds is -2.
In the anions of oxyacids, oxygen is always assigned an oxidation number of -2. Therefore, in an MnO4-1 anion, manganese must have an oxidation number of +7 to achieve electrical balance for the anion. (There is no neutral compound with the formula MnO4.)
