+8 is the usually quoted maximum oxidation number. Osmium tetra-oxide has this. +7 is fairly common as manganese in KMnO4 has this oxidation number.
Minimum oxidation number: -3, Maximum oxidation number: 5
4, 3, 2, 1 (weakly basic oxide) Maximum Oxidation number: 4 Minimum Oxidation number: 0
The oxidation number of magnesium is +2. Any other for this element would be energetically unfavorable and unstable.
Aluminum has a valency of 3, its maximum oxidation number is 3. Nearly all of its compounds have Al with oxidation number +3.
The maximum oxidation number is theoretically equal to the number of valence electrons. For example the oxidation number of chlorine among different compounds can vary from -1 to +7. An exception for this is fluorine, which only have -1 and 0 as its oxidation numbers.
Minimum oxidation number: -3, Maximum oxidation number: 5
Potassium's minimum oxidation number is zero.Its maximum is plus one.
4, 3, 2, 1 (weakly basic oxide) Maximum Oxidation number: 4 Minimum Oxidation number: 0
Sulphur has 6 valence electrons. So its maximum oxidation number is +6.
The oxidation number of magnesium is +2. Any other for this element would be energetically unfavorable and unstable.

0 in the elemental form, +2 and +3 (most common) in its compounds. But osmium can form compounds with oxidation number up to +8 (maximum)
Nine
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.
-3 is most common, but maximum will be +5
Minimum oxidation number: -1 Maximum oxidation number: 1 Min. common oxidation no.: 0 Max. common oxidation no.: 1 I got this of a really cool website that has alot of infromation and useful facts about each element and trust me you'll use it a lot in chemistry. www.chemicool.com
