Rubidium in excess oxygen gives the superoxide RbO2.
Like other alkali metals, Rubidium metal reacts violently with water.
Similar to other metals, Rubidium metal reacts violently with water.
Rubidium has also been reported to ignite spontaneously in air.

Rubidium carbonate(Rb2CO3), which is used in some optical glasses,
and Rubidium copper sulfate, Rb2SO4·CuSO4·6H2O.
Twenty four additional Rubidium isotopes have been synthesized with half-lives of less than
3 months;
Rubidium forms a number of oxides when exposed to air,
including Rubidium monoxide(Rb2O), Rb6O, and Rb9O2;
Other common Rubidium compounds are the corrosive Rubidium hydroxide(RbOH),
the starting material for most Rubidium-based chemical processes;
Rubidium vapor is optically pumped by a laser
and the polarized Rb polarizes 3He by the hyperfine interaction.
After reduction of the hexachloroplatinate with hydrogen, this process yielded 0.51 grams of Rubidium chloride for further studies.

He investigated emission spectra of heated elements,
and discovered caesium(in 1860) and Rubidium(in 1861) with the physicist Gustav Kirchhoff.
It occurs naturally in the minerals pollucite, leucite, carnallite and zinnwaldite, which contain as much as 1% Rubidium oxide.
Rubidium has a number of oxides,
including Rubidium monoxide(Rb2O), Rb6O and Rb9O2, which form if Rubidium metal is exposed to air;
The resonant element in
atomic clocks utilizes the hyperfine structure of Rubidium's energy levels, and Rubidium is useful for high-precision timing.
Rubidium occurs in pollucite, carnallite, leucite, and zinnwaldite, which contains traces up to 1%, in the form of the oxide.
For several years in the 1950s and 1960s, a by-product
of potassium production called Alkarb was a main source for Rubidium.
Both potassium and Rubidium form insoluble salts with chloroplatinic acid,
but these salts show a slight difference in solubility in hot water.

Navigation satellite IRNSS-1I has been launched to replace
India's first navigation satellite IRNSS-1A, whose three Rubidium atomic clocks had stopped working two years ago.
The slight radioactivity of Rubidium was discovered in 1908,
but that was before the theory of isotopes was established in 1910, and the low level of activity(half-life greater than 1010 years) made interpretation complicated.

To prove the effectiveness of their technique, the researchers bathed a structure they had built with light and studied the result with a CCD camera-
it was able to highlight the fluorescence of the Rubidium atoms showing their locations within the microtrap.
Among historical scientific achievements of Heidelberg researchers features prominently the invention of spectroscopy, and of the Bunsen burner;
the discovery of chemical elements Caesium and Rubidium; the identification of the absolute point of ebullition;
and the identification and isolation of nicotine as the main pharmacologically active component of tobacco.
