2.3 Flashcards
What is a transition element?
A d-block element that forms an ion with an incomplete d sub-shell.
What is a complex ion?
A transition metal ion bonded to one or more ligands by coordinate bonds.
What is a ligand?
A molecule or ion that can donate a pair of electrons with the transition metal ion to form a coordinate bond.
What is the coordination number?
The total number of coordinate bonds formed between a central metal ion and its ligands.
What is a stereoisomer?
Species with the same structural formula but with a different arrangement of atoms in space.
What is ligand substitution?
A reaction in which one ligand in a complex ion is replaced by another ligand.
What is the 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.
