Which halogen can form only one oxidation state other than zero?
i think its fluorine but im not sure if its right but i do believe that it is not right
Fluorine, the most electronegative element in the periodic table, has a -1 oxidation state in its compounds, and a zero oxidation state in the free element, F2. So you are correct that is is correct and not correct in your believe it is not correct. How's that for confusing?
The halogen that can form only one oxidation state other than zero is fluorine (F).
To determine this, we need to look at the elements in the halogen group, which includes fluorine, chlorine, bromine, iodine, and astatine.
One way to find the oxidation states of the elements is by examining their position in the periodic table. Halogens are found in group 17, also known as Group VIIA or Group 7.
In general, halogens have a valence electron configuration of ns²np⁵, where n represents the energy level. This configuration allows them to gain one electron to achieve a stable octet (i.e., eight valence electrons) in their outermost electron shell.
However, the halogen with the highest electronegativity and smallest atomic size is fluorine. Being the most electronegative element, fluorine tends to gain an electron to achieve a stable noble gas configuration of neon. As a result, fluorine almost always has an oxidation state of -1 in its compounds.
In contrast, the other halogens (chlorine, bromine, iodine, and astatine) can exhibit multiple oxidation states. Their less electronegative nature and larger atomic sizes allow for the sharing or loss of electrons, resulting in different oxidation states.
To summarize, only fluorine (F) can form just one oxidation state other than zero, which is -1.
