Exam preparation:

1
Exam preparation

• Unit analysis is critically important
• The values you calculate must have the correct
  units!
• Familiarity with the use of scientific notation
  and prefixes for units (e.g. kg, mg, ng) in
  calculations is expected
• For example the skills described above are used
  in density and specific heat calculations

2
Exam preparation

• Differences and similarities between Dalton,
  Rutherford and Bohr models for the atom
• Atomic symbol notation (i.e. mass number, atomic
  number, charge on ion)
• Definitions of terms (and calculations)
  associated with atomic structure, mass
• Periodic properties (radius, ionizaiton energy,
  metals vs. non-metals)

3
Exam preparation

• What is a quantum jump?
• Range of visible spectrum and relationship to
  ultraviolet and infrared regions.
• How to calculate wavelength of light that is
  emitted (or absorbed) when an electron jumps from
  one energy level to another
• How to calculate a value for the energy of light
  when you are given its wavelength

4
Exam preparation

• What is a valence electron?
• Definitions of electron shells, subshells,
  valance shell.
• Ground state vs. excited state
• How to determine the ground state electron
  configuration for an atom or ion
• Relationship between the organization of the
  periodic table and the electronic structure of
  atoms

5
Exam preparation

• Lab 1
• Density calculations
• Error in measurement
• Lab 2
• Calculation of light energy
• Calculation of energy differences between shells
• Calculation of the wavelength of light emitted in
  a line spectrum
