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.
Ricky Gervais (pictured in 2010) played the lead, a down-on-his-luck actor. Portrayed by Ricky Gervais, Andrew "Andy" Millman is the lead character of Extras.Andy's dream to become an actor – he left his steady day job at NatWest in Wokingham in order to pursue it – is endlessly thwarted by the fact that his agent Darren Lamb is incompetent, circumstances seem to conspire against him, and ...

Similar to potassium permanganate, the two-step decomposition of rubidium permanganate leads to the formation of rubidium manganate intermediates. It breaks down into manganese dioxide, rubidium oxide and oxygen. [4] The decomposition temperature is between 200 and 300 °C. [7] Drift-away oxygen caused an 8% mass loss in the product. [7]
Rubidium selenide is an inorganic compound composed of selenium and rubidium. It is a selenide with a chemical formula of Rb 2 Se. Rubidium selenide is used together with caesium selenide in photovoltaic cells .
Rubidium hexafluorotitanate is an inorganic compound of rubidium, fluorine, and titanium with the chemical formula Rb 2 TiF 6. [1] [2] [3] Physical properties.
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 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 ) .
