The oxidation numbers of halogens can vary because they have seven valence electrons, making it possible for them to gain or lose different numbers of electrons to attain a stable electron configuration. This flexibility allows halogens to exhibit a range of oxidation states in chemical compounds, such as -1, +1, +3, +5, +7.

What is Oxidation number of halogens?
Halogens typically have an oxidation number of -1 in compounds because they have seven valence electrons and need to gain only one electron to achieve a full octet. Exception: in compounds with oxygen or other halogens, halogens may have positive oxidation numbers.
What element has -1 as an oxidation number?
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.
What is the common oxidation number for all halogens?
The common oxidation number for halogens is -1. This is because halogens have 7 electrons in their outer shell and tend to gain 1 electron to achieve a full valence shell, resulting in an oxidation number of -1.
The oxidation number of halogens is?
The oxidation number of halogens is typically -1 when they are in compounds. This is because halogens tend to gain one electron to achieve a full outer shell, resulting in a negative charge.
What is the oxidation number of iodide?
The oxidation number of iodide is -1. Iodine is in Group 17 of the periodic table, commonly known as the halogens, which typically have an oxidation number of -1 when in ionic compounds.
Can an oxidation number be 1?
Yes. All of the halogens usually have this oxidation number in their compounds.

In the compound Fe2O3 iron's oxidation number is plus 3 and oxygen's oxidation number is .?
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).
What is the oxidation number of iodide?
The oxidation number of iodide is -1. Iodine is in Group 17 of the periodic table, commonly known as the halogens, which typically have an oxidation number of -1 when in ionic compounds.
What are the oxidation states of halogens?
The oxidation states of halogens can range from -1 to +7. Fluorine typically has an oxidation state of -1, while the other halogens (chlorine, bromine, iodine) can have oxidation states from -1 to +7 depending on the compound and bonding.
How do you find the oxidation number for chlorine?
To find the oxidation number of chlorine, consider that chlorine typically has an oxidation number of -1 in its compounds. However, in certain situations, such as when bonded with oxygen or other halogens, chlorine can have different oxidation states. It's important to follow the usual oxidation number rules and balance the charges in the compound to determine the oxidation number of chlorine.
When do halogens show 1 and -1 oxidation states?
When halogens bind to more electropositive elements (compared it itself), they show -1 oxidation state. When halogens bind to more electronegative elements (compared it itself), they show +1 oxidation state.
Do the halogens have different numbers of valence electrons?
no, but lower halogens have different oxidation states.
What is the oxidation state of all halogens?
-1
