Goal I. Write and interpret equations for nuclear reactions. 

Objectives: To meet the requirements of Goal I, you must be able to:

  1. distinguish between a chemical reaction and a nuclear reaction. 
  1. classify given nuclear reactions with respect to the nuclear process represented, and the mode of radioactive decay (Table 24.2)
  1. distinguish between an induced nuclear reaction and a radioactive decay process.
  1. complete an equation for a nuclear reaction which has a missing reactant or product .

Goal II. Understand the basic concepts underlying the model for nuclear decay and induced nuclear reactions.

Objectives: To meet the requirements of Goal II, you must be able to:

  1. describe the mechanisms by which the emission of radiation is detected by a Geiger counter, a scintillation counter and by a solid-state ionization detector.
  1. relate the activity of a radioactive sample to its rate of decay.
  1. use the mathematical model of first order kinetics to calculate half-life, rate constant, rate of decay, time and/or amount of sample remaining for a given radioactive decay process.
  1. interpret a graph of neutron number vs. proton number for the known nuclides  (Figure 24.2)  with respect to:
    • the “band of stability,” 
    • predicting activity in terms of half-life,
    • predicting the mode of radioactive decay,
    • consequences of odd or even numbers of nucleons for stability of isotopes.
  1. interpret a diagram illustrating a radioactive decay series. (Figure 24.3)

Goal III. Apply the principles underlying the energetics of nuclear reactions .

Objectives: To meet the requirements of Goal III, you must be able to:

  1. use the Einstein equation, E = mc2 (or E = mc2) to calculate the energy of a given nuclear reaction.
  1. calculate the mass defect of a given nuclide and convert mass defect into nuclear binding energy per nucleus and per nucleon.
  1. interpret a graph of binding energy per nucleon vs. mass number (Figure 24.13).
  1. describe the process of nuclear fission.
  2. describe and compare the process of nuclear fusion with nuclear fission.

Goal IV. Interpret and translate between complete structural, condensed structural and line formulas for organic compounds and selected types of isomers.

Objectives: To meet the requirements of Goal IV, you must be able to:

  1. distinguish between straight chain and branched chain hydrides of carbon (hydrocarbons) writing complete structural formulas from condensed structural formulas and vice versa.

  1. define and recognize constitutional isomers or structural isomers. Table 15.3.

Goal V. Recognize and correctly name simple hydrocarbons and compounds containing common organic functional groups. 

Objectives: To meet the requirements of Goal V, you must be able to:

  1. distinguish among alkane (p. 623), alkene (p. 628) and alkyne (p. 31) hydrocarbons.
  2. memorize the prefixes associated with carbon chains from one to ten carbon atoms in length.
  3. identify and name the main chain in an alkane and any side chain alkyl groups.
  4. memorize the names and formulas for the common functional groups (Table 15.5.)
  5. define the term aromatic with respect to the structure of an organic compound (p.632).

Goal VI. Understand the fundamentals of polymer formation and the control of polymer properties.

Objectives: To meet the requirements of Goal VI, you must be able to:

  1. recognize formulas for the monomer units and abbreviated polymer formulas (Table 15.6)
  2. explain the process of chain polymerization by:
  • defining chain reaction, initiator, chain propagation, chain termination;
  • diagramming (with chemical formulas) the sequence of steps in the process (Fig. 15.25).
  1. explain the difference between addition polymers and condensation polymers.
