  1. Definitions

  2. Transition metal complex • A ‘molecule’ with a transition metal at the centre • Ligand • The molecule or ion that binds to the central metal in a complex • Coordinate group • Another word for ligand, if the ligand is a molecule Transition metal (Pt) ligands Coordinate groups

  3. Parts of the atom • Add/subtract a proton: creates a different atom • Add/subtract a neutron: creates a different isotope • Add/subtract an electron: changes oxidation state • / creates ion

  4. Isotopes of hydrogen • 3 forms of hydrogen: • Protium, deuterium, tritium • Differ only in the number of neutrons they have • Adding another proton would make it helium Diagram from Microsoft Encarta

  5. at·om [áttəm] • (pluralat·oms) n • 1. smallest part of element: the smallest portion into which an element can be divided and still retain its properties, made up of a dense, positively charged nucleus surrounded by a system of electrons. Atoms usually do not divide in chemical reactions except for some removal, transfer, or the exchange of specific electrons. • They are the single elements as they appear on the periodic table • They are neutral (have no charge)

  6. mol·e·cule [móllə kyl] • (pluralmol·e·cules) n • 1. CHEMISTRYsmallest part of a chemical compound: the smallest physical unit of a substance that can exist independently, consisting of one or more atoms held together by chemical forces. • Two or more atoms that are joined together by covalent or ionic bonding

  7. Ion • i·on [ ən, òn] • (plurali·ons) n • electrically charged atom or atom group: an atom or group of atoms that has acquired an electric charge by losing or gaining one or more electrons
