Why hard hard interactions are ionic?

Similarly, you may ask, which bonding is involved in hard hard interaction?
Furthermore, what is a hard ligand? Hard bases/ligands have a more concentrated, less polarizable electron pair. Examples are F- and HO-. A ligand is essentially a Lewis base (since it donates an electron pair to the complex). Hard bases/ligands have a more concentrated, less polarizable electron pair. Examples are F- and HO-.
Furthermore, why do hard acids prefer hard bases?
The theory elaborates that hard acids prefer to bond with hard bases, and the resulting adduct tend to have more ionic character in its bonding. Correspondingly, soft acids prefer to bond with soft bases, and their adducts are more covalent in nature.
What are soft and hard metals?
Class A metals are metals that form hard acids. Hard acids are acids with relatively ionic bonds. These metals, such as iron, aluminium, titanium, sodium, calcium, and the lanthanides, would rather bond with fluorine than iodine. Soft acids are acids with relatively covalent bonds.
