Transition element
A d-block element that forms an ion with an incomplete d sub-shell.
1 of 7
Complex ion
A transition metal ion bonded to one or more ligands by coordinate bonds.
2 of 7
Ligand
A molecule or ion that can donate a pair of electrons with the transition metal ion to form a coordinate bond.
3 of 7
Coordination number
The total number of a coordinate bonds formed between a central metal ion and its ligands.

Ligand substitution
A reaction in which one ligand in a complex ion is replaced by another ligand.
5 of 7
Stability constant, Kstab
The equilibrium constant for an equilibrium existing between a transition metal ion surrounded by water ligands and the complex formed when the same ion has undergone a ligand substitution.
