We elaborate the uses of Rubidium and atomic properties with characteristics. Rubidium is a whitish silver-looking chemical element with atomic number 37. Its symbol is Rb and it belongs to the group of alkali metals and its usual state in nature is solid. Rubidium is located at position 37 on the periodic table.
On this page you can discover the chemical properties of rubidium and information about rubidium and other elements on the periodic table such as potassium, cesium, strontium or hydrogen. You will also learn what rubidium is for and you will know what its uses are through its properties associated with rubidium such as its atomic number or the usual state in which rubidium can be found.
You will be able to see rubidium qualities such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in rubidium atoms and other properties.
For some elements some of this information is unknown. In these cases we show the properties attributed to them.
Properties of rubidium
Rubidium belongs to the group of alkali metals. This group of elements is characterized by having a single electron at its outermost energy level and they tend to lose it, thus forming a monopositive ion. This tendency of alkali metals such as rubidium is due to their low ionization energy and their low electronic affinity.
The state of rubidium in its natural form is solid. Rubidium is a whitish silver-looking chemical element and belongs to the group of alkali metals. The atomic number of rubidium is 37. The chemical symbol for rubidium is Rb. The melting point of rubidium is 312.46 degrees Kelvin or 40.31 degrees Celsius or degrees Celsius. The boiling point of rubidium is 961 degrees Kelvin or 688.85 degrees Celsius or degrees Celsius.
Uses of rubidium
Rubidium is a highly reactive, silver-white color. This metal was discovered in 1861 by German chemists. Rubidium is a relatively common element in the Earth’s crust. Most rubidium is extracted from lepidolite, this is a mineral that contains approximately between 0.3 and 3.5% of that element. Rubidium has few industrial applications. If you have ever wondered what rubidium is for , here is a list of its possible uses:
- Rubidium is used to make atomic clocks from low-cost rubidium. These atomic clocks are used for a variety of purposes such as in global navigation systems (GPS and GLONASS) and within the telecommunications industry (mobile phone base stations and television stations).
- It is used in laser cooling, which is used to cool molecular and atomic samples.
- Rubidium salts are used to make certain types of glass and ceramic products.
- Rubidium is used to remove traces of gases in the vacuum tubes.
- An isotope of rubidium, Rb82, is used in certain types of medical imaging. This isotope is commonly used to detect and brain tumors to improve the medical image of the heart in overweight patients.
- This metal is used in the manufacture of photoelectric cells and serves to achieve the purple color in fireworks.
Rubidium Atomic Properties
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find rubidium within the periodic table of the elements, rubidium is in group 1 and period 5. Rubidium has an atomic mass of 85.4678 u.
The electronic configuration of rubidium is [Kr] 5s1. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The median radius of the rubidium is 235 pm, its atomic radius or Bohr radius is 265 pm, its covalent radius is 211 pm, and its Van der Waals radius is 303 pm. Rubidium has a total of 37 electrons whose distribution is 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 it has 8 electrons and in the fifth layer it has 1 electron.
