Rubidium (pronunciation roo-BID-ee-em [2]), represented by the chemical symbol (molecular formula) Rb [1, 12], is a soft element belonging to the family of alkali metals [1, 2]. It has 29 isotopes with known half-lives the mass numbers of which range from 74 to 102. The naturally...
“None of the lines belong to any previously known body. Amongst them are two which are particularly remarkable in lying beyond Fraunhofer’s line in the outermost portion of the red solar spectrum. Hence we propose for this new metal the name rubidium (and the symbol Rb) from the Latin...
