Rubidium - an overview | ScienceDirect Topics

Rubidium (Rb) is an alkali metal with two isotopes (85 Rb and 87 Rb) that is present in trace quantities in rocks. Due to the similarities between the valence state (1 +) and ionic radius (1.48 Å) of Rb + and those of K + (1.33 Å), Rb easily substitutes for K in mineral structures. Strontium (Sr) is an alkaline earth element with four stable isotopes (84 Sr, 86 Sr, 87 Sr and 88 Sr).
