How was rubidium named?
Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named after the two prominent red lines of its spectrum.
Where is rubidium found?
It is relatively rare, although it is the 16th most abundant element in the earth’s crust. Rubidium is present in some minerals found in North America, South Africa, Russia, and Canada. It is found in some potassium minerals (lepidolites, biotites, feldspar, carnallite), sometimes with caesium as well.
Does the human body use rubidium?
Rubidium is not particularly harmful to humans, and once in the body its ions are rapidly excreted in sweat and urine. Rubidium chloride has been used to study the transport of potassium ions in humans, since rubidium ions are not naturally found in the body and when present they are treated as if they were potassium.
Why Rubidium is not used in schools?
Why is the reason behind rubidium not being used in schools? Rubidium is a soft, silvery-white metallic element of the alkali metal group, with a standard atomic weight of 85.4678. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air.
Is cesium found in the human body?
Humans may be exposed to cesium by breathing, drinking or eating. In air the levels of cesium are generally low, but radioactive cesium has been detected at some level in surface water and in many types of foods.
Why is rubidium so expensive?
Rubidium is a rare and expensive metal with few uses. Ironically, its rarity in part is due to there being few recipes that mark Rb as an important ingredient. It have a solitary extra electron in its outer shell means it will hungrily pair up with almost any other element and form an especially strong bond.
Is Mercury costlier than gold?
The increase in the mercury price over the last year (almost tripling from $650/flask to $1,850/flask) has actually outpaced the rise in gold prices making the relative cost of using mercury to extract gold higher. It is interesting to consider what the price of mercury in the future will signify.
