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 is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [9] Rubidium is the first alkali metal in the group to have a density higher than water.
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.
This causes lithium to form the oxide exclusively on reaction with oxygen at room temperature. This effect becomes drastically weaker for the larger sodium and potassium, allowing them to form the less stable peroxides. Rubidium and caesium, at the bottom of the group, are so large that even the least stable superoxides can form.
Inorganic ozonides [1] are dark red salts. The anion has the bent shape of the ozone molecule.. Inorganic ozonides are formed by burning potassium, rubidium, or caesium in ozone, or by treating the alkali metal hydroxide with ozone; this yields potassium ozonide, rubidium ozonide, and caesium ozonide respectively.
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest.
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 ) .
