The chemical name for peroxide is hydrogen peroxide, often written as H2O2.
Formula: O22-
Equation: O22- + I- ----> O2- + I2
a.O2 b. O2+ C. O2- d. O22-
The bond order of C22 is 1, as it is a monatomic molecule with only one carbon atom. Bond order represents the number of chemical bonds between atoms and determines the stability of a molecule.
Yes oxygen can form the oxide ion O2-, and the peroxide ion O22-
O2 is the most stable form among the options listed. O2 is the common diatomic oxygen molecule found in our atmosphere. O2+ is a less stable oxygen ion with a positive charge, while O22 is not a commonly encountered species.
Ionic, Na2O with Na+ ions and O2- ions Also forms a peroxide Na2O2 with Na+ and O22-
The oxidation number of oxygen atoms in O2 is 0 because oxygen generally exhibits a zero oxidation state in elemental form.
The oxidation state of O in K2O2 is -1. This is because the overall charge of the ion (O22-) is -2, and there are two oxygen atoms, leading to an individual oxidation state of -1 for each oxygen atom.
The chemical symbol for hydrogen peroxide is H2O2.
If you mean O2, then it is a molecule, though it would be more appropriate to call it "double oxygen" than "double oxide." Though it is usually just called oxygen. If you main O22-, then it is an ion, not a molecule or atom. It is called the peroxide ion.
