+1 oxidation state
The oxidation number of Mn in manganese VII oxide is +7.
The oxidation number of NO, nitrogen oxide, is +3.
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
the oxidation number for potassium is 1.
KO2 is rare and is called potassium superoxide. It consists of K+ ion and O^2- ion. In this case, the oxidation number of O would be 1-. If, however, you meant to ask about K2O (potassium oxide), then the oxidation number of O would be 2-
The chemical formula for potassium metaperiodate is KIO4. The oxidation number of potassium is +1.
KCo3
The oxidation number of Mn in manganese VII oxide is +7.
Potassium's minimum oxidation number is zero.Its maximum is plus one.
The oxidation number of NO, nitrogen oxide, is +3.
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
Potassium's oxidation number is +1. Chromium's oxidation number is +6. Oxygen's oxidation number is -2.
2+
I am going to assume you meant ferrous oxide. Ferrous oxide is also known as Iron(II) oxide and has the formula unit FeO. The oxidation number of iron in iron(II) oxide is +2.
