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.
