While Bohr’s model considers an atom of one element as a separate quantum system (and the atomic number is included in the theory as a parameter, so that there are as many quantum systems as there are elements), in the Rumer–Fet model, atoms of various elements are considered as ...
cesium (Cs),chemical elementof Group 1 (also called Group Ia) of theperiodic table, thealkali metalgroup, and the first element to be discovered spectroscopically (1860), by German scientistsRobert BunsenandGustav Kirchhoff, who named it for theuniqueblue lines of its spectrum (Latincaesius, ...

the silvery white element itself does not occur free in nature. It was first isolated in 1808 bySir Humphry Davy, who evaporated themercuryfrom a magnesiumamalgammade byelectrolyzinga mixture of moist magnesia and mercuric oxide. The namemagnesiumcomes from Magnesia, a district ofThessaly(Greece)...

the copper atoms that diffused out of the target were element-selectively laser-ionized by the ISOLDE resonance ionization laser ion source (RILIS) in a hot cavity. The ions were then accelerated to 30 keV for mass separation using the ISOLDE high resolution separator and prepared for high-resol...

In this case, it must be reverted to the text of the PrimaryLanguage. 4 Description mechanisms 4.1 Referencing Each element that can be referenced within the IODD contains an explicit attribute "id". The referencing element contains a type-dependent attribute with the following composition: Id ...
Following the classical research on elastic strain, the Hooke element is adopted to denote the elastically deformed behavior of the soil. For the visco-plastic creep strain, to fit the progression tendency of the strain–time curves in Figure 5, Figure 6, Figure 7, Figure 8, Figure 9, Figu...
