Chapter 22: Chemistry of Selected Transition Elements and Coordination Compounds 22.1 Properties of the Transition ( d -Block) Elements 22.2Iron and Steel: The Use of Pyrometallurgy 22.3Copper: A Coinage Metal 22.4Silver and Gold: The Other Coinage Metals 22.5Chromium 22.6Coordinate Covalent Bonds: Complex Ions and Coordination Compounds Coordinate covalent bond is when one atom contributes both electrons for the shared pair Metals and Coordination Compounds o Transition metals can form covalent bonds with molecules or ions that have lone pair electrons; vacant d orbitals can accept lone pairs into orbitals o Complex ions are ions formed in which several molecules or ions are connected to a central metal ion or atom by coordinate covalent bonds o Ligands are the molecules or ions bonded to the central metal ion; has one or more atoms with lone pairs that can form coordinate covalent bonds to metal ion o Charge of complex ion is determined by charges of metal ion and charges of ligands o Coordination compounds are compounds that contain metal ions surrounded by ligands; usually brightly colored Naming Complex Ions and Coordination Compounds
