Why is rubidium dangerous?
Intact skin provides a degree of protection, but the metals also react with the fat layer that protects the skin. In addition they are very flammable, rubidium and cesium can ignite spontaneously on contact with air. Their fires cannot be extinguished with water, as that would result in a very violent reaction.
What is the approximate melting point?
The melting point of a compound is the temperature at which it changes from a solid to a liquid. This is a physical property often used to identify compounds or to check the purity of the compound. It is difficult, though, to find a melting point. Usually, chemist can only obtain a melting point range of 2 - 3( C accuracy.

Which is the best estimate of the melting point of rubidium?
In terms of their physical properties, the elements of Group 1 are soft metals with low-melting points. Rubidium is no exception to this rule, being silvery-white and melting at 39 ºC.
How do you know the melting point of an element?
The melting point of an organic solid can be determined by introducing a tiny amount into a small capillary tube, attaching this to the stem of a thermometer centred in a heating bath, heating the bath slowly, and observing the temperatures at which melting begins and is complete.

Which substance has the highest melting and boiling point?
Though not entirely adequate for your purposes, one of the substances (if not the substance) with the highest temperature range between melting and boiling at ambient pressure is gallium, which melts at 30°C and boils at 2400°C. That's an amazingly huge liquid range of 2370°C!
What is the temperature of rubidium?
Rubidium is a very soft, ductile, silvery-white metal. It is the second most electropositive of the stable alkali metals and melts at a temperature of 39.3 °C (1 02.7 °F). Like other alkali metals, rubidium metal reacts violently with water.
What is the atomic number of Rubidium?
Rubidium is the chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silvery-white metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, ...
How is rubidium kept?
To ensure safety and purity, this metal is usually kept under dry mineral oil or sealed in glass ampoules in an inert atmosphere . Rubidium forms peroxides on exposure even to a small amount of air diffused into the oil, and storage is subject to similar precautions as the storage of metallic potassium.
What is the most common compound used in the manufacture of rubidium?
Rubidium chloride (RbCl) is probably the most used rubidium compound: among several other chlorides, it is used to induce living cells to take up DNA; it is also used as a biomarker, because in nature, it is found only in small quantities in living organisms and when present, replaces potassium. Other common rubidium compounds are the corrosive rubidium hydroxide (RbOH), the starting material for most rubidium-based chemical processes; rubidium carbonate (Rb 2 CO 3 ), used in some optical glasses, and rubidium copper sulfate, Rb 2 SO 4 ·CuSO 4 ·6H 2 O. Rubidium silver iodide (RbAg 4 I 5) has the highest room temperature conductivity of any known ionic crystal, a property exploited in thin film batteries and other applications.
How long does rubidium last?
Twenty four additional rubidium isotopes have been synthesized with half-lives of less than 3 months; most are highly radioactive and have few uses.
How many isotopes are in rubidium?
On Earth, natural rubidium comprises two isotopes: 72% is a stable isotope 85 Rb, and 28% is slightly radioactive 87 Rb, with a half-life of 49 billion years—more than three times as long as the estimated age of the universe .
Where is rubidium found?
Two notable sources of rubidium are the rich deposits of pollucite at Bernic Lake, Manitoba, Canada, and the rubicline ( (Rb,K)AlSi3O8) found as impurities in pollucite on the Italian island of Elba, with a rubidium content of 17.5%. Both of those deposits are also sources of caesium.
