The number of electrons in each of Rubidium's shells is 2, 8, 18, 8, 1 and its electronic configuration is [Kr] 5s 1. The rubidium atom has a radius of 247.5.pm and a Van der Waals radius of 200.pm. Rubidium is highly reactive, with properties similar to other Group 1 elements, e.g., rapid oxidation in air.
Rubidium is a chemical element of group 1 (the first column on the periodic table) with the abbreviation Rb and atomic number 37. As a member of the alkali metals, rubidium has an oxidation state of +1.

Its launch became imperative after all three rubidium atomic clocks on IRNSS-1A failed in mid-2016, Mr. Kumar told The Hindu. Three more clocks failed later across the fleet of seven satellites, which together had 21 atomic clocks.
PRS10 Rubidium Oscillator. The PRS10 is an ultra-low phase noise, 10 MHz rubidium-disciplined crystal oscillator. The device fulfills a variety of communication, synchronization and instrumentation requirements. The phase noise of the 10 MHz output is low enough to be used as the reference source for synthesizers.
This is perfect for operating with different backup time or frequency sources. The S250 can also revert to a Stratum 2 mode and retrieve time from other user-designated time servers. Similarly the S250 generates IRIG B, 1PPS and 10 MHz outputs and can be upgraded to an internal Rubidium atomic oscillator.

Atomic Clocks. Clocks locked to atomic standards are much more stable timekeepers. Rubidium, Cesium and Hydrogen Maser clocks are very accurate. Of the three, Rubidium clocks often provide the best combination of cost, size and overall performance and are often a requirement for high reliability master clock systems.

atoms in a rubidium cell with an internal vapor source. The cell is an evacuated glass bulb, which is characterized in that the source of atomic vapors in the form of a metal film Rb is evenly distributed throughout the inner surface of the bulb, and the paraffin film is uniformly distributed over the entire area and over the metal surface.
A rubidium clock is an atomic clock which uses rubidium atoms and an “optical pumping” technique to measure the atomic transition frequency. A rubidium Atomic clock includes 87Rb isotope confined in a vapor cell. The atoms are excited to a high energy level (in figure #1) by light emitted by other 87Rb atoms.
An atomic clock is a clock device that uses an electron transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element.
