Yes first of all, u know that a atom can have maximum of 2 valence electron or 8electrons right?? so if two atoms which has 1 v. electron bond, its oxidation can be +1 or -1. Also the same thing applies to the 8 valence electron, if there is two '4 v. electroned' atom, it can be +4 or -4..
the oxidation state/number can also change depending on the compound that the element is in.....
for example normally oxygen is -2 however in peroxide compounds it is -1

∙ 12y agoThe transition elements have d orbitals underneath their valence shells. These electrons can be moved from the d shell to the valence shell and can then be donated in oxidation. For a few of the transition elements valence electrons can also be moved into the d suborbital where they generally cannot be donated.

∙ 12y agoBecause in transition elements the energy difference between 's' and 'd' orbital is very small, therefore electrons from both orbitals can participate in bond formation.

Do all elements in a group have the same oxidation numbers?
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
What group of elements can have more then 1 oxidation number?
Predominantly, the transition elements, but also hydrogen, nitrogen, and oxygen. Actually all elements that have reactions can have more than one oxidation number in the sense that their oxidation number is 0 when they are in pure form and usually is some other value when they are in compounds.
How can an elements Oxidation number be found?
In some periodic tables
Oxidation numbers for five common transition elements?
Transition elements usually have more than one oxidation number. In different oxidation numbers, the ions show different colors. Some of the ranges: Cu from +1 to +2; Cr from +2 to +6; Ni from +2 to +3; Co from +2 to +3 and Mn from +2 to +7.
Which elements have oxidation number 1?
Potassium and Lithium

Why some elements has more than one oxidation number?
An element in which there are at least two almost equally energetic highest energy electrons can have more than one oxidation number, because some reagents will involve only one of these high energy electrons and other reagents or reaction conditions may involve more than one.
What is true about oxidation-reduction reactions?
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
What is the oxidation number of group 17 elements?
There are some numbers. Every element shows -1 number.
What are the raw materials for oxidation?
Well, you generally need some atoms, which will have some electrons obviously. The movement of the electrons generally relates to a change in oxidation state, and hence the chemical process of oxidation (and reduction) has occurred.
What are some common ions with changing oxidation numbers?
Some of the elements exhibiting variable oxidation numbers are carbon (+4, -4); oxygen and selenium (-2 to +6); nitrogen and phosphorus (-3 to +5) halogens (except fluorine) (-1 to +7) and most of the transition metals and f block elements.
What is the name of the Atom?
It depends on which oxidation state the atom is in some possibilities are carbide carbonate
