rubidium

 [roo-bid´e-um]
a chemical element, atomic number 37, atomic weight 85.47, symbol Rb. (See Appendix 6.)
rubidium 82 a radioactive isotope of rubidium having a half-life of 1.273 minutes and decaying by positron emission. It is used as a tracer in positron emission tomography.

ru·bid·i·um (Rb),

(rū-bid'ē-ŭm),
An alkali element, atomic no. 37, atomic wt. 85.4678; its salts have been used in medicine for the same purposes as the corresponding sodium or potassium salts.

rubidium (Rb)

[roo͡bid′ē·əm]
Etymology: L, rubidus, reddish
a soft metallic element of the alkali metals group. Its atomic number is 37; its atomic mass is 85.47. Slightly radioactive, it is used in radioisotope scanning.
