Factors Affecting Stability of Complex Compound

Stability of complex compound $\propto$ oxidation state of central meta atom.
Stability of complex compound $\propto$ charge on central metal atom.
Stability of complex compound is inversely proportional to central metal atom.
Stability of complex compound $\propto$ electronegativity of central metal atom.
Stability of complex compound $\propto$ charge on ligands.
Stability of complex compound is inversely proportional to the size of ligands.
Chelating ligands which form 5-6 membered ring complex compound are far more stable than any other complex compound.
