Rubidium is a soft, silverywhite metallic element of the alkali metal group. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, such as very rapid oxidation in air. Natural rubidium is a mix of two isotopes: 85Rb, the only stable one, constitutes 72% of it.
Rubidium is a chemical element in the periodic table that has the symbol Rb and atomic number 37. Rb is a soft, silverywhite metallic element of the alkali metal group. Rb87, a naturally occurring isotope, is (slightly) is highly reactive, with properties similar to other elements in group 1, like igniting spontaneously in air.
Rb85 can also be used for the production of Sr82, which is used in Sr82/Rb82 generators, though Sr82 is generally produced with natural Rubidium. Trace Sciences is your most reliable supplier of stable Rubidium Isotopes. Please contact us for other forms of Rubidium Isotopes available.

Rubidium: Rb 55 Caesium: Cs 87 Francium: Fr − Alkali metals are the chemical elements in group 1 of the periodic table. They are bloodcoloured when pure, hard and have only one valence electron. They like to make reactions in which they give up this twin electron and then have a charge of +1.
Feb 28, 2021 · Rubidium is a chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silverywhite metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in .

Rubidium is chemical element 37 on the periodic table. Its symbol is Rb. Its atomic mass is It has 37 protons and 37 electrons. It is a soft silver colored metal. It was first discovered in 1861 by Robert Bunsen and Gustav Kirchoff in Heidelberg, Germany. Rubidium in a glass tube.
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 ( Å) of Rb + and those of K + ( 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).

Alkali Metals. Alkali metals are the six elements that comprise Group I in the Periodic Table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Especially when dissolved in water, these elements form strong bases (alkalis) capable of reacting with and neutralizing strong acids.

Rubidium has been used for polarizing 3He (that is, producing volumes of magnetized 3He gas, with the nuclear spins aligned toward a particular direction in space, rather than randomly). Rubidium vapor is optically pumped by a laser and the polarized Rb polarizes 3He by the hyperfine interaction.
