Naming polyatomic ions and acids Definition Polyatomic ions are similar to monatomic ions in that they both have an ionic charge (+ or -). Polyatomic ions are made of two or more atoms that act as a unit Examples ? Naming compounds with polyatomic ions Nitrate ion NO3-1 Phosphate ion PO4-3 Sulfate ion SO4-2 Ammonium ion NH4+1 Naming polyatomic ions The name of the ion usually ends in either -ite or -ate. The -ite ending indicates a low oxidation state (NO-2 ion - nitrite ion). The -ate ending indicates a high oxidation state (NO-3 ion - nitrate ion). Naming polyatomic ions Prefixes also can be used. The prefix hypo- indicates the very lowest oxidation state. (ClO- ion - hypochlorite ion)

preAP Chem 2013-2014 1 Name ________________________________ Note: It is very important that you note that some elements do not occur as single atoms when by themselves. If they are not combined with another element, they will bond with themselves, forming a _________________ molecule. In any chemical reaction, when you see these elements alone, they must be shown with a diatomic formula. Diatomic elements: H2, N2, O2, F2, Cl2, Br2, I2 I. Describing Chemical Change A. Writing Equations ? words can be used to describe _____________________________, but that can become long and ______________________. ? chemists use ___________________________ to describe reactions. In chemical equations,

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)
