Transition element
A d block element that forms an incomplete ion with an incomplete d sub shell
Complex ion
Transition metal bonded to one or more ligand a by coordinate bonds
Ligand
Molecule or ion that can donate a pair of electrons with the transition metal ion to form coordinate bind
Coordination number
Total number of coordinate bonds formed between Central metal ion and its Ligands
Stereoisomers
Species with same structural formula but different arrangement of atoms in the space
Optical isomers
Non superimposible mirror images of each other
Ligand substitution
Reaction in which one ligand in a complex ion is replaced by another ligand, one binds more strongly
Stability constant
The equilibrium constant existing for an equilibrium existing between a transition metal ion and the complex formed when the same ion had undergone a ligand substitution
