| 説明 | Rubidium (Rb) is # 37 on the Periodic Table of Elements. Elemental rubidium is a silvery-gray metal. It is produced by mining rocks rich in lepidolite mica, a lithium mica mineral. Lepidolite has minor quantities of Rb.Thirty-six isotopes of rubidium are known - two occur naturally. Most Rb (about 72%) is rubidium-85. Rubidium-87 is slightly radioactive and makes up about 28% of Rb.-----------------------------Info. at:en.wikipedia.org/wiki/Rubidiumanden.wikipedia.org/wiki/Isotopes_of_rubidium |
