with another atom, the electronegativity describes the tendency of the atom to pull the bonding valence electrons towards itself. Bonding different atoms together creates a chemical compound. The dominance of ionic or covalent bonding is predicted by considering the electroengativity values of the ...
Considering the general importance of inorganic aluminum chalcogenides to applied research, it is of prime interest to understand the aggregation processes that create the bulk materials from single atoms and to clarify the nature of the chemical bond between the elements. Theoretical calculations, as ...
