Interparticle correlations and chemical bonding from physical side: Covalency $\text{versus}$ atomicity and ionicity

Ewa Brocławik, Maciej Fidrysiak, Maciej Hendzel +1

In this Chapter we reexamine the concept of $\text{covalency}$ and $\text{ionicity}$ on example of the simplest molecules. First, starting from the exact expression for the two…
