Strontium (atomic symbol: Sr, atomic number: 38) is a Block S, Group 2, Period 5 element with an atomic weight of 87.62 . The number of electrons in each of Strontium's shells is [2, 8, 18, 8, 2] and its electron configuration is [Kr] 5s2. The strontium atom has a radius of...
The excitation of 3 D levels of strontium atom by slow monoenergetic electrons has been studied experimentally. Thirty six excitation cross-sections were measured at 30-eV electron energy. Optical excitation functions for most of the transitions were recorded in the 0–200-eV electron-energy range....

Small oscillations of the atomic scattering amplitude beyond absorption edges are used for site-selective study of coordination geometry7. Other methods rely on the dependence of the scattering amplitude on the X-ray ...
Strontium has the symbol Sr, the atomic number 38 and an atomic weight of 87.623 g/mol. As an alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. Due to its extreme reactivity with oxygen and water, this element occurs ...
IntroductionThe symbol of strontium is Sr, and the atomic number is 38. It is the fourth member of the second main group of the periodic table. Strontium is a typical alkaline earth element. The electronic structure is a structure with two additional external 5s electrons. Strontium is an alk...
, and these salts are used in pyrotechnics and in the production of flares.[9] Like calcium and barium, as well as the alkali metals and the divalent lanthanides europium and ytterbium, strontium metal dissolves directly in liquid ammonia to give a dark blue solution of solvated electrons.[8...
of the SrCl2, as a moltenelectrolyte in a graphite dish-shaped electrolysis apparatus. This process produces Sr cations collected at the cathode, where they acquire electrons to form strontium metal. At the same time,Cl- anions give up electrons at the anode and are released as chlorine gas ...
