How is the magnitude of `Delta_(0)` affected by (i) nature of ligand and (ii) oxidation state of metal ion ?

Explanation

(i) `Delta_(0)` is affected by nature of ligand. Greater the strength of ligand, greater is the value of `Delta_(0)`·
(ii) `Delta_(0)` is also affected by oxidation state of central metal ion.
Generally, higher the ionic charge on the central metal ion, the greater will be the value of Ao·
