As a consequence, Bohr was able to reproduce the Periodic Table, adding one electron at a time as one stepped to the next higher element. Bohr argued that orbits of increasing radius could accommodate up to a maximum number of electron numbers that, when reached, corresponded to observed ...
distribution of electron density for the states of the hydrogen atom is obtained by photographing a special model; the dimensions of the “electron cloud” grow approximately in proportion ton2, which corresponds to an increase of the radius of the orbit according to formula (6) in Bohr’s ...

When the ratio of the radius of the interstitial atom to that of the metal atom is greater than 0.41 but less than 0.59, interstitial compounds are formed; hydrides, borides, carbides and nitrides of the transition metals are common examples. These compounds usually take up a simple structure...
In the years to come he extended the theory to encompass all elements and to provide an explanation of the Periodic Table. The Bohr radius (52.9 × 10 −12 m) and the Bohr magneton (9.27 × 10 −24 J/T) are today used as units of measure. In 1922 Bohr received the Nobel Prize...
The size of the blockade radius, among other things, depends on the energy of the Rydberg state and the intensity of the exciting lasers. On the other hand, higher-lying Rydberg states are more susceptible to noise, because of their strong dipole moment. Using the mobile optical traps, it ...
where E, A, R, and N are the electronegativity, electron affinity, radius, the number of outermost electrons, respectively, and the subscripts X and C refer to dopant and carbon, respectively. As shown in Fig. 3a and Supplementary Table 4, \(\varDelta {G}_{{H}_{2}^{\ast }}^{\...
Then the cutoff shell of principal cluster is determined by the atomic close-packing principle14,22, as shown in the inset map (a) of Supplementary Figure S3, the cutoff radius (r) of cluster shell corresponds to the maximum radial atomic density (ρra). Thereof, the principal cluster and...
