FeO (Ferrous oxide) or Fe2O3 (Ferric oxide).
FeO, FeO₂, and Fe₂O₃
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
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 answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
Atomic oxygen has oxidation number 0. Molecular oxygen also has 0 as oxidation number. It would be the same for five oxygen molecules as well.
In H2PO4-, oxygen has the formal oxidation number -2, phosphorus has the formal oxidation number +5, and hydrogen has the formal oxidation number +1. The formal oxidation numbers for oxygen in almost all oxyanions and for hydrogen in almost all acid anions have these values, so that the remaining element can be assigned a formal oxidation number by the requirement of satisfying the total electrical charge if any shown in the formula.
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
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 oxidation number of oxygen is -2 in most of its compounds
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
In the compound Co2O3 cobalt has an oxidation number of 3 while oxygen has an oxidation number is -2.
Atomic oxygen has oxidation number 0. Molecular oxygen also has 0 as oxidation number. It would be the same for five oxygen molecules as well.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
In H2PO4-, oxygen has the formal oxidation number -2, phosphorus has the formal oxidation number +5, and hydrogen has the formal oxidation number +1. The formal oxidation numbers for oxygen in almost all oxyanions and for hydrogen in almost all acid anions have these values, so that the remaining element can be assigned a formal oxidation number by the requirement of satisfying the total electrical charge if any shown in the formula.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
the most common oxidation number for oxygen is -2.
It is a neutral oxide. Oxygen shows -2 oxidation number.
In FeO the oxidation number of iron is 2+ and the oxidation number of oxygen is 2-.
