Rb, a chemical element in group I of Mendeleev's periodic system. Atomic number, 37; atomic mass, 85.4678. A silver-white alkali metal, rubidium occurs in nature as a mixture of the two isotopes—stable 85 Rb (72.15 percent) and weakly radioactive 87 Rb (half-life T ½ = 4.8 × 10 10 years). With beta decay, 87 Rb forms stable 87 Sr. The geological age of rocks and minerals can be reliably .

Alkali metal - Simple English Wikipedia, the free encyclopedia

Alkali metals are the chemical elements in group one of the periodic system. They are blood-coloured 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. They react strongly with water and because of this, they have to be stored in oil. Alkali metals are the first group in the periodic table.
