Upon completing this section, the student should be able to:

 

1.  Recognize, use, distinguish between, and /or give examples of the following:

            ·Atom, molecule, compound, mixture

            ·Electron, proton, neutron, nucleus

            ·Atomic number, mass number, atomic mass, isotopes

            ·Ions, anions, cations

 

2.  Describe, define and/or recognize models of the atom and the person’s name

       associated with the model including: Dalton’s model, Thomson’s Model,

       Rutherford’s Model, and the current or modern model.

 

3.  Recognize, draw, label, explain the operation and the significance of the following:

            ·Thomson’s Cathode Ray Tube

            ·Millikan’s Oil Drop Experiment

            ·Gold Foil Experiment

            ·Mass Spectrometer

 

4.  Recognize, define and/or describe the properties of:

            ·Alpha particles

            ·Beta Particles

            ·Gamma Rays

 

5.  Write symbols for isotopes showing atomic number and mass number.

 

6.  If provided some (but sufficient) information about an element including – symbol,

     atomic number, mass number, number of protons, number of electrons, number of

     neutrons, determine the parameter that is missing from the list.

 

7.  If given the percent abundance and amu for the isotopes of an element, calculate the

     atomic mass of the element.
