Rubidium upptäcktes första gången av Robert Bunsen och Gustav Kirchhoff i Heidelberg 1861 genom att använda spektroskopi. På grund av de ljusa röda linjerna i strålningen valde de ett latinskt namn, rubidus, som har betydelsen mörkröd. Bunsen var även den förste att framställa metalliskt rubidium, vilket han gjorde genom reduktion ...

Přírodní rubidium je směsí stabilního izotopu 85 Rb a radioaktivního 87 Rb s poločasem rozpadu 4,9.10 10 let. Uměle bylo připraveno dalších 27 radioaktivních izotopů s nukleonovými čísly 74 až 102.

The NRC is considering amending the requirement in § 35.63, "Determination of dosages of unsealed byproduct material for medical use," to clarify that, for the incremental administration of rubidium-82, dose measurements do not have to be complete before administration when the dose is measured continuously during the infusion of Rb …

Rubidium is an active element on Earth, but whether and how its isotopes fractionate during geological processes are not known yet. In this study, we present data showing large variations in δ 87 Rb in bulk samples and individual mineral species from a granite weathering profile in South China as well as in surrounding stream water. The …

Twenty four isotopes of rubidium are known. Naturally occurring rubidium is made of two isotopes, 85 Rb and 87 Rb. Rubidium-87 is present to the extent of 27.85% in natural rubidium and is a beta emitter with a half-life of 4.9 x 10 10 years. Ordinary rubidium is sufficiently radioactive to expose a photographic film in about 30 to 60 days.

The electronic configuration of Rubidium is: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 1. Rubidium(Rb) is an alkali metal present in the fifth row of the table, having higher density than water. Identified for its silvery texture, Rb is reactive to water and air and hence often kept sealed.Oxidation state of +1 is common in Rb.

Rubidium is no exception to this rule, being silvery-white and melting at 39 ºC. The element has two naturally occurring isotopes. Rubidium-85 is the dominant form, accounting for 72 per cent of the total, while most of the remainder is the radioactive rubidium-87, which has a half-life of 50 billion years.

The market is expected to grow during 2022–2027 [45]. 3. Brine as an alternative source for rubidium recovery. Rb recovery requires several intricate steps, making the recovery of pure Rb from land mining challenging and unsustainable in terms of chemical requirement, process intensity, and economic cost.

Rubídium (rubidium) je chemický prvok v Periodickej tabuľke prvkov, ktorý má značku Rb a protónové číslo 37. Rubídium patrí medzi alkalické kovy, vyznačuje sa veľkou reaktivitou a mimoriadne nízkym redox-potenciálom.Je to mäkký, ľahký a striebrolesklý kov, ktorý mimoriadne rýchlo, až explozívne, reaguje s kyslíkom i vodou a v prírode sa s ním preto …

Rubidium iodide crystals are widely used for manufacturing various opti- cal components employed especially in the infrared region. This is due to the fact that RbI crystals exhibit a broad range of transparency from the near UV (0.24/xm) to the far IR (64/xm). RbI is the most hygroscopic material of the rubidium halides.
