+3
-1 Oxidation
Bromine has an oxidation number of negative one, except when with oxygen or flourine.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
-1 for bromine in bromide
+3
-1 Oxidation
Bromine has an oxidation number of negative one, except when with oxygen or flourine.
Br2 + H20 ===> HBr + HOBr
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
-1 for bromine in bromide
Bromine has an oxidation number of negative one, except when with oxygen or flourine.
Actually there are a few KBrO3 or NaBrO3 etc - in the bromate ion, bromine is in oxidation state +7
Bromine gas (or bromine in any other state of matter except plasma) is a chemical element, and the oxidation number of any element in its elemental state is zero by definition.
zero for each bromine
The molecular formula should be CBr4. The oxidation numbers are -1 for each Br, +4 for C.
Bromine has the valence -1.
