By the end of this section, you will be able to: Derive the predicted ground-state electron configurations of atoms Identify and explain exceptions to predicted electron configurations for atoms and ions Relate
Heavy atoms and ions offer an interesting opportunity to study atomic physics in a region where the atomic structure is dominated by the interelectronic interactions. One illustration of this is the profound term dependence of atomic orbitals for certain configurations of heavy atoms and ions. This ...
The dominant ionization mechanism in most multicharged ion sources is stepwise impact ionization in successive collisions of atoms and ions with energetic electrons. Multiple ionization in a single collision with an electron must also be accounted for in accurate models of charge-state abundances in ho...

Fig. 2. Atomic beam apparatus for electron-beam excitation of Li atoms to Rydberg states.(From reference [10].) On the positive side, electron impact excitation is easy and works with all atoms. On the negative side, it is not at all state-selective and produces ions as well as Rydberg...
4.Electron configurations for ions: For example: The atomic number of nitrogen is seven. Its notation for electron configurations is 1s22s22p3. It has 5 valence electrons. So the element has itsoxidizingnumber from–3 to +5. (怎么读?) But most common oxidizing number is +3 and +5. The...
In an intense X-ray free-electron laser (XFEL) pulse, atoms are sequentially ionised by multiple X-ray photons. Photoionisation generally induces an alignment of the electron cloud of the produced atomic ion regarding its orbital-angular-momentum project
Investigate varying electron configurations in electron shells around an atom's nucleusAtomic model of electron configurations. See all videos for this article An ordinary, neutral atom has an equal number of protons (in the nucleus) and electrons (surrounding the nucleus). Thus the positive and ne...
