Rubidium is a chemical element of the periodic table, its symbol is Rb and its atomic number is 37. It is a metal with highly reactive characteristics, its color is silvery white and is very soft. It is found in nature in an extremely dispersed state. It is usually obtained from lithium production. Rubidium is used in photoelectric cells and for certain types of catalysts.
This is an element of the periodic table discovered in 1861 by German scientists, whose symbol is the Rb and its atomic number is 37. It is very reactive, silvery white and soft to touch. It is rarely found in nature and is obtained from the production of lithium.
This metal was discovered in 1861 by German chemists. It was discovered in 1860 by the German physicist Gustav Robert Kirchhoff and the chemist Robert Wilhelm Bunsen, through the spectral analysis of Durkheim mineral water. The element was named after its characteristic red spectrum lines (from the Latin ‘rubidus’, dark red).
It has a density / g of dm-3: 1532. Its molar volume/cm3mol-1 is: 55.79. As for its thermal properties we can mention the following characteristics:
As for the ionization characteristics, we can mention the following aspects
Rubidium is an element that belongs to the group of alkaline metals. This group of elements is characterized because they have only one electron in their most external energy level and have a tendency to lose it, being this the form they have to form a mono-positive ion. This tendency that alkaline metals have is because they have a low ionization energy and their electronic affinity is very little. The state of rubidium in its natural form is solid.
It is a silvery whitish chemical element and belongs to the group of alkaline metals. Its atomic number is 37, its symbol is Rb, its melting point is 312.46 degrees Kelvin or 40.31 degrees Celsius or degrees Celsius and its boiling point is 961 degrees Kelvin or 688.85 degrees Celsius or degrees Celsius.
It has a total of 37 electrons distributed as follows: In the first layer it has 2 electrons, in the second it has 8 electrons, in its third layer it has 18 electrons, in the fourth, 8 electrons and in the fifth layer it has 1 electron. Its melting point is 312.46 K and its boiling point is 961 K. It has an electrical conductivity of around 7.79-106S/m and a thermal conductivity of 58.2 W/(Km).
Rubidium is a highly reactive element and its color is usually silvery white. It is a relatively common element in the earth’s crust. The majority of it is extracted from lepidolite, this is a mineral that contains approximately between 0.3 and 3.5% of that element.
Rubidium actually has very few industrial applications. Some of its possible uses are the following:
There are few real important applications of this chemical element. The spectral line that gives it its name is one of them, as well as the purple color of some fireworks. Its other applications have to do mostly with the fact that rubidium has a high vapor pressure.
It is a mineral that may be beneficial for the treatment of depression. Studies have recommended that the right amount for humans is 1 to 5 milligrams. However, there is no defined set of recommended daily allowance, as this element is a trace element. Rubidium is responsible for carrying nutrients to organs, but only in small amounts.
