Expert Answer
Oxygen forms oxides as well as peroxides and super oxides.
In peroxides, the two extra electrons go into antibonding orbitals, reducing the bond order to one.
The peroxide can be viewed as an oxygen molecules with two extra electrons.
Metals that can form ionic peroxides include the alkali metals, calcium, barium, and strontium.
The superoxide molecule can be viewed as an oxygen molecule with an extra single electron and has a bond order of one and a half.
Metals that can form ionic superoxides include potassium, rubidium, and cesium.
