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.

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 do you know which oxidation to use in a bond when it has multiple oxidation numbers?
You can determine the correct oxidation number to use by balancing the overall charge of the compound. Additionally, consider the electronegativity of the elements involved in the bond to determine the more likely oxidation state. In some cases, experimental data or rules of thumb based on common oxidation states for specific elements may also help in deciding the correct oxidation number to use.
Elements with an oxidation number of 1 include what?
The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
Elements with an oxidation number of 2 include which of the following?
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.

Why does chlorine have an oxidation number of 1?
Chlorine has 7 valence electrons and requires one more electron to complete the octet. Hence it has an oxidation number of -1. But, it should be noted that chlorine show positive oxidation numbers (up to +7) also in its compounds
How can an elements Oxidation number be found?
The oxidation number of an element is typically determined based on its position on the periodic table and known oxidation rules. For example, in compounds, the sum of oxidation numbers must equal the overall charge. For atoms in their elemental form (such as O2 or Na), the oxidation number is zero.
Which elements have oxidation number 1?
Potassium and Lithium
Can Chlorine oxidation number ever be negative two?
No, that is not possible for Chlorine. Some elements have more than one oxidation number, such as Iron, Mercury, Copper, etc, but Chlorine only wants to gain one electron. If it had a -2 charge, it would not be stable, so that would never happen.
What elements have oxidation number 3?
There many with +3 oxidation.Some are Al, Fe, Bi.
What is the oxidation number for just sulfur?
Elemental sulphur, like all other elements, has an oxidation number of zero(0). However, when combined with other elements into molecules, it displays different oxidation number.s H2S = -2 SO2 = +4 SO3 = +6 H2SO4 = + 6
What is the oxidation number of group 17 elements?
The oxidation number of group 17 elements, also known as the halogens, is typically -1. This is because they have seven valence electrons and tend to gain one electron to achieve a full outer shell configuration.
