What has rubidium?

Answer 1

Commercially it's mined from the ore lepidolite. It's present in several other minerals as well. It's actually fairly common ... about as common in the Earth's crust as zinc, and more common than copper, though since it's highly reactive it's never found in an uncombined state.

Answer 2

Rubidium chloride (RbCl) is probably the most used rubidium compound; it is used in biochemistry to induce cells to take up DNA, and as a biomarker since it is readily taken up to replace potassium, and occurs in only small quantities in living organisms. Other common rubidium compounds are the corrosive rubidium hydroxide (RbOH), the starting material for most rubidium-based chemical processes; rubidium carbonate (RbCO3), which is used in some optical glasses, and rubidium copper sulfate, Rb2SO4•CuSO4•6H2O. Rubidium silver iodide (RbAg4I5) has the highest room temperature conductivity of any known ionic crystal, a property that is being exploited in thin film batteries and other applications.

Rubidium-82 is used for positron emission tomography. Rubidium is very similar to potassium and therefore tissue with high potassium content will also accumulate the radioactive rubidium. One of the main uses is in myocardial perfusion imaging. The very short half-life of 76 seconds makes it necessary to produce the rubidium-82 from decay of strontium-82 close to the patient. As a result of changes in the blood brain barrier in brain tumors, rubidium collects more in brain tumors than normal brain tissue, allowing to use the radioisotope rubidium-82 in nuclear medicine to locate and image brain tumors.

Rubidium was tested for the influence on manic depression and depression. Dialysis patients suffering from depression show a depletion in rubidium and therefore a supplementation may help during depression. In some tests the rubidium was administered as rubidium chloride with up to 720 mg.

It is also used in atomic clocks.

Answer 3

rubidium is a one of the 115 elements in the Periodic Table its atomic number is 37 it is used in gas scavenger in vacums

Answer 4

Rubidium is found in several types of minerals. It is frequently found in such specimens as zinnwaldite, pollucite, carnallite, and leucite.

Answer 5

Rubidium is classified as a metal and its in the group of alkali metals. Its atomic number is 37, its atomic weight is 85.4678, and its melting point is 102.76 degrees Fahrenheit.
