For most elements, their highest attainable oxidation number is equal to the number of valence electrons. Examples are the maximum oxidation numbers for: sulfur is +6, phosphorus is +5 and chlorine is +7. Fluorine is an exception which bears oxidation numbers 0, -1/2 and -1.

In per chloric acid HClO4, the oxidation number of chlorine is +7.
Nickel is in the d block. Ni shows +3 as the highest.
Atomic number is not related to oxidation number. If you want to find the atomic number of a particular element, all you have to do is find it on the periodic table of elements.
This is a neutral compound. Oxidation number of it is +2.

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.

hydrogen peroxide
The answer to this question is that the oxidation number for the 2nd energy level is +2. This is because the 2nd energy level is the second highest energy level in an atom, and thus has a higher oxidation number than the 1st energy level. The oxidation number for the 2nd energy level is determined by the number of electrons in the 2nd energy level.
It has plus 7 oxidation state.It is in highest oxidation state.
