Rubidium and cesium often occur together in nature.
Rubidium forms two other oxides (Rb2O and Rb2O3). Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named Organic compounds that contain the functional group −N=C=O are known as isocyanates. Rubidium atomic clocks, or frequency standards, have been constructed, but they are not as precise as cesium atomic clocks.

Propionitrile, also known as ethyl cyanide and propanenitrile, is an organic compound with the formula CH3CH2CN. The name is also used for the CN radical, and hence is used for compounds such as cyanogen bromide (NCBr). Caesium cyanide has chemical properties similar to potassium cyanide and is very toxic. HCN is produced on an industrial scale and is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals.
