The rubidium content in minerals is often calculated and quoted in terms of Rb 2 O. In reality, the rubidium is typically present as a component of (actually, an impurity in) silicate or aluminosilicate. A major source of rubidium is lepidolite, KLi 2 Al(Al,Si) 3 O 10 (F,OH) 2, wherein Rb sometimes replaces K. Rb 2 O is a yellow colored solid.
Rubidium forms a number of oxides when exposed to air, including rubidium monoxide (Rb 2 O), Rb 6 O, and Rb 9 O 2; rubidium in excess oxygen gives the superoxide RbO 2. Rubidium forms salts with halogens, producing rubidium fluoride , rubidium chloride , rubidium bromide , and rubidium iodide .
Rubidium sesquioxide is a chemical compound with the formula Rb 2 O 3 or more accurately Rb 4 O 6.In terms of oxidation states, Rubidium in this compound has a nominal charge of +1, and the oxygen is a mixed peroxide (O 2− 2) and superoxide (O − 2) for a structural formula of (Rb +) 4 (O − 2) 2 (O 2− 2).

Rubidium superoxide or rubidium hyperoxide is a chemical compound with the chemical formula RbO 2. In terms of oxidation states, the negatively charged superoxide and positively charged rubidium give it a structural formula of Rb + [O 2] −. [2]
Rubidium ozonide is an oxygen rich compound of rubidium. It is an ozonide , meaning it contains the ozonide anion (O 3 − ). It can be created by reacting rubidium superoxide (RbO 2 ) with ozone (O 3 ) in a liquid ammonia solution.
It reacts with carbon dioxide to form lithium carbonate and oxygen. Sodium peroxide (Na 2 O 2) is a pale yellow solid that melts at 460 °C and decomposes at 657 °C. Potassium peroxide (K 2 O 2) is a yellow solid that melts at 490 °C. Rubidium peroxide (Rb 2 O 2) is produced when rubidium stands in air.
In addition to the neutral rubidium oxalate Rb 2 C 2 O 4, there is also an acidic salt, rubidium hydrogen oxalate with the formula RbHC 2 O 4, which is isomorphic to potassium hydrogen oxalate KHC 2 O 4 [10] and forms monoclinic crystals, [11] and an acidic dioxalate with the formula RbHC 2 O 4 ·H 2 C 2 O 4, which exists as a dihydrate, has a ...
