Complex Ions Complex ion - ionic species consisting of a metal ion bonded to one or more Lewis bases Coordinate bond - bond formed when one anion/molecule donates a pair of electrons to another ion/molecule to form a covalent bond Ligand - a Lewis base bonded to the central metal ion of a complex ion Common Ligands (Lewis Bases): NH3, H2O, OH-, Cl-, CN- Inner coordination sphere - ligands that are bound directly to a metal via coordinate covalent bonds Counter ions - ions that balance the electrical charges of complex ions in coordination compounds Ex: [Ag(NH 3 ) 2 ] + + Cl - ?> [Ag(NH 3 ) 2 ]Cl Coordination compound - any compound that contains a complex ion Coordination number - identifies the number of electron pairs surrounding a metal ion in a

Chapter 6 ?Chemical Names and Formulas? By Stephen L. Cotton, Charles Page High School Modified by Barbara Williams, DeBakey HSHP H2O Molecular Compounds Molecule Neutral chemically bonded group of atoms that act as a unit Usually composed of 2 or more nonmetal atoms Make up molecular compounds Ions and Ionic Compounds Ion Charged atom or group of atoms (cation or anion) Cation name: same name + ?ion? (Na+ is called ?sodium ion?) Anion name: root name ends with ?-ide? (Cl- is called ?chloride?) Ionic Compound Composed of metal cation and nonmetal anion An Anion is? A negative ion. Has gained electrons. Nonmetals can gain electrons. Charge is written as a superscript on the right. F1- Has gained one electron (-ide is new ending = fluoride) O2- Gained two electrons (oxide)
