ESSENTIAL UNIT 3 (E03)
(Electron Configuration and the Periodic Table)
(June 2011)
Unit Statement: Unit three introduces the Bohr and quantum mechanical models of the
atom, electron configurations, the uncertainty principle, and arrangement of the periodic
table.
Essential Outcomes: (must be assessed)
1. The Student Will summarize the Bohr model of the atom. (p. 129)
2. TSW analyze what the quantum mechanical model determines about the electrons
in an atom. (p.130)
3. TSW explain how sublevels of principle energy levels differ. (p. 131-132)
4. TSW summarize the three rules for writing the electron configurations of
elements. (p. 134-137
5. TSW interpret the cause of atomic emission spectra. (p. 138-142)
6. TSW describe how the modern periodic table is organized. (p. 162)
7. TSW summarize the information found in the periodic table. (p. 164-169)
8. TSW classify elements based on electron configuration. (p. 170-172)
9. TSW explain how ions are formed. (p. 176)
10. TSW analyze periodic trends in atomic size, ionization energy, ionic size, and
electronegativity. (p. 174-182)
Introduced and Practiced Outcomes:
1. The Student Will explain what causes electron emission spectra. (p.140)
2. TSW contrast quantum mechanics and classical mechanics (p. 147)
3. TSW contrast early attempts at organizing elements with Mendeleev’s method.
(p. 160-161)
