-2 for each O, +7 for Mn
In the anions of oxyacids, oxygen is always assigned an oxidation number of -2. Therefore, in an MnO4-1 anion, manganese must have an oxidation number of +7 to achieve electrical balance for the anion. (There is no neutral compound with the formula MnO4.)
oxidation number of I is -1. oxidation number of F is +1.
The oxidation number for H is +1, and the oxidation number for O is -1.
Oxidation number of o is -2. Oxidation number of H is +1.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.

fluorine oxidation number is -1
Oxidation number of o is -2. Oxidation number of H is +1.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
+1 for each Na -1 for oxygen (as it is peroxide)
In LiH the oxidation number of Li (lithium) is 1+ and the oxidation number of H (hydrogen) is 1-
Pottasium has +1 oxidation number.Iodine has -1 oxidation number.
The oxidation number of F, or Fluorine, is F-1. Since it is in the seventh group on the periodic table, it has seven valence electrons. It needs to get eight valence electrons to be stable, so it will gain one electron.
