2 O) or lithia is an inorganic chemical compound. It is a white solid. Although not specifically important, many materials are assessed on the basis of their Li 2 O content. For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. [2]
Iodine dioxide is a binary inorganic compound of iodine and oxygen with the chemical formula IO 2. [1] [2] Only stable as a dilute gas, [3] this compound is one of many iodine oxides, [4] [5] and "iodine dioxide" is sometimes used to describe its formal dimer, the salt diiodine tetroxide (I 2 O 4, [IO] + [IO 3] −).
Lithium peroxide is the inorganic compound with the formula Li 2 O 2. Lithium peroxide is a white solid, and unlike most other alkali metal peroxides, it is nonhygroscopic. Because of its high oxygen:mass and oxygen:volume ratios, the solid has been used to remove CO 2 from and release O 2 to the atmosphere in spacecraft. [4]
The LiO 2 molecule is a misnomer: the bonds between lithium and oxygen are highly ionic, with almost complete electron-transfer. [1] The force constant between the two oxygen atoms matches the constants measured for the superoxide anion (O − 2) in other contexts.
Iodine pentoxide (I 2 O 5) Iodine oxides are chemical compounds of oxygen and iodine . Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide , but a number of other oxides are formed in trace quantities or have been hypothesized to exist.
The iodite ion, or iodine dioxide anion, is the halite with the chemical formula IO − 2. Within the ion, the iodine exists in the oxidation state of +3.

Io is considered to be the most volcanically active body in our solar system. Pele type volcanism is believed to be the cause of sulfur components in the atmosphere. Volcanic plumes pump 10 4 kg of SO 2 (sulfur dioxide) per second into Io's atmosphere on average, though most of this is deposited back onto the surface.
