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.
Can a element have more than one oxidation number?
Yes, an element can have multiple oxidation numbers. The oxidation number of an element can vary depending on the compound it is in and its chemical environment. For example, the oxidation number of iron can be +2 or +3 in different compounds.
What does the common oxidation number mean?
The common oxidation number means any number that indicates the charge of atoms when an electron is either lost, gained, or shared in a chemical bond. It is known as the ion's number. Also, oxidation numbers in all atoms in a compound must add up to zero.
Which property is common to all halogens?
Halogens are all non-metals, they are all very reactive, and they are all colorful.
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.
Can an oxidation number be 1?
Yes. All of the halogens usually have this oxidation number in their compounds.
What is the oxidation state of all halogens?
-1

What is the common oxidation number for all elements in group 17 of the periodic table?
-1.

What is the most common oxidation number of sodium?
0 in elemental form, +1 in all its compounds
Which properties do the halogens have in common?
All halogens are very reactive chemical elements anf form anions.

Oxidation number astatine?
Astatine has a valency of 1, because it is in group 7 and is part of the halogens. They say the group number is the number of valence, but the valency can't be 7. So they do 8 (the number of total outer shells allowed) - the group number if it's above 4. 8 - 7 = 1. And all the other halogens, in group 7 like fluorine, chlorine, bromine and iodine have a valence of 1. All in all, Astatine has a valency of 1.
What features do all the halogens have in common?
Thier all in the same periodic group
