What is the most common oxidation state of the chalcogens compared to the halogens?
The most common oxidation state of the chalcogens (group 16 elements) is -2, as they typically gain two electrons to achieve a stable electron configuration, especially in compounds like sulfides. In contrast, the halogens (group 17 elements) commonly exhibit an oxidation state of -1, as they usually gain one electron. Both groups can exhibit positive oxidation states, but the -2 state is characteristic of chalcogens, while -1 is characteristic of halogens.

Which halogen naturally exists in positive oxidation no?
Fluorine is the only halogen that does not naturally exist in any positive oxidation state. The other halogens - chlorine, bromine, iodine, and astatine - can exist in various positive oxidation states, though they are less common in nature compared to their negative oxidation states.
Which group is known as halogens in peridic table?
Group 7 are Halogens. The most common are Flourine, Chlorine, Iodide, however, there are more
What elements combine with californium?
Californium can react with oxygen, hydrogen, sulfur, nitrogen, halogens, etc.
When does iron show the 4th oxidation state?
Never. iron shows either +2 or +3 oxidation state but in Fe3O4 its oxidation state is seems to +4 but it is actually mixture of one moles FeO and one mole Fe2O3 , (FeO.Fe2O3 = Fe3O4).
What is the oxidation state of Li in a reactant?
Minimum oxidation number: -1 Maximum oxidation number: 1 Min. common oxidation no.: 0 Max. common oxidation no.: 1 I got this of a really cool website that has alot of infromation and useful facts about each element and trust me you'll use it a lot in chemistry. www.chemicool.com
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?
Most common is -1. But halogens (except fluorine) are known to exhibit oxidation numbers upto +7 in their compounds.
Which halogen naturally exists in positive oxidation no?
Fluorine is the only halogen that does not naturally exist in any positive oxidation state. The other halogens - chlorine, bromine, iodine, and astatine - can exist in various positive oxidation states, though they are less common in nature compared to their negative oxidation states.
What is the oxidation number of halide ions?
Fluorine: -1 Chlorine: -1, +1, +3, +5, +7 Bromine: -1, +1, +3, +5, +7 Iodine: -1, +1, +3, +5, +7 The normal oxidation state of halides is -1, but with, for example, chlorine other oxidation states exist. Hypochlorites (+1), Chlorites (+3), Chlorates (+5), Perchlorates (+7). The same is true for all halogens, with the exception of fluorine, that seems to like it's -1 status and won't form fluorates.
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.
Which properties do the halogens have in common?
All halogens are very reactive chemical elements anf form anions.
