Chemical Nomenclature Review Chemical Formulas Identify a compound. Use subscripts to tell how many of each element. Subscript outside of ( ) distributes only to the elements inside of the ( ). Ions Are charged particles: protons ? electrons Types of Ions Cations (metals) positive charge after LOSING electron(s) Anions (nonmetals) negative charge after GAINING electron(s). Monotomic: formed from a single atom. Polyatomic: formed from more than one type of atom. Ions ATOM Chlorine Bromine Sulfur Oxygen Iodine ION Chloride Bromide Sulfide Oxide Iodide Types of Nomenclature Based on First Element!!! Type I: Metal / Non-metal Type II: Transition Metal / Non-metal Type III: Non-metal / Non-metal Example - Metal is from Groups 1, 2 or 13 Type 1

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)

Chemistry 1210: General Chemistry Dr. Gina M. Florio 06 September 2012 Lecture Notes Jespersen, Brady, Hyslop, CH 3 Elements, Compounds, and the Periodic Table Structure of the Atom Atom consists of smaller (subatomic) particles: Protons (positively charged) Neutrons (no charge) Electrons (negatively charged) Found in the atomic nucleus e ?1 0 Electrons H+ 1 1 p 1 1 , Protons and n 0 1 Neutrons Matter is typically neutral ? equal number protons and electrons per atom Size: If diameter of nucleus = 1 foot, then diameter of atom ~ 1.9 miles! Ch. 3.1 2 Chapter 1.6 Identification of Atoms Each atom has two ID numbers: 1. Atomic Number (Z) Z = Number of protons Element ? a substance whose atoms contain the same number of protons ? a substance with a unique atomic number, Z Isotope

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)
