4.Remember that chemical reactions occurbecause atoms have valence electrons, which are electrons in their outer shell.When the outer shell is “unfilled” or the required number of electrons is notyet complete, the atom is more reactive. Noble gases have a full outer shell,meaning that they ...
We use a complex scaled configuration interaction (CSCI) method for the three active electrons supplemented with a sophisticated model potential as developed by Laughlin [Phys. Scr. 45, 238 (1992)] to account for core-valence interactions. The CI calculations are based on Mg(+) and Ca(+) ...
