  • Coordination Complex
    A compound consisting of a complex ion and counter ions, often colored and paramagnetic due to transition metals.
  • Complex Ion
    A charged species with a metal cation bonded to ligands, enclosed in brackets.
  • Ligand
    A molecule or ion that donates an electron pair to a metal cation, acting as a Lewis base.
  • Lewis Acid
    An electron pair acceptor, typically a metal cation in coordination chemistry.
  • Lewis Base
    An electron pair donor, often a ligand in coordination complexes.
  • Counter Ion
    An ion that balances the charge of a complex ion, maintaining overall neutrality.
  • Oxidation Number
    A value representing the total number of electrons an atom gains or loses to form a chemical bond.
  • Coordination Number
    The number of ligand atoms bonded to the central metal cation in a complex.
  • Chelating Agent
    A ligand that forms multiple bonds with a single metal ion, enhancing stability.
  • Monodentate Ligand
    A ligand that donates a single pair of electrons to a metal ion.
  • Bidentate Ligand
    A ligand that donates two pairs of electrons to a metal ion, forming a ring.
  • Polydentate Ligand
    A ligand that donates multiple pairs of electrons to a metal ion, forming several bonds.
  • EDTA
    A hexadentate ligand used to bind metal ions, found in many everyday products.
  • Tetrahedral Geometry
    A molecular shape formed when a metal ion is bonded to four ligands.
  • Octahedral Geometry
    A molecular shape formed when a metal ion is bonded to six ligands.
