Unit 3 - Electrons, Atoms, and Periodic Trends

Learning Targets

  • LO 1.5 The student is able to explain the distribution of electrons in an atom or ion based upon data.

LO 1.6 The student is able to analyze data relating to electron energies for patterns and relationships.

LO 1.7 The student is able to describe the electronic structure of the atom, using PES data, ionization energy data, and/or Coulomb’s Law to construct explanations of how the energies of electrons within shells in atoms vary.

LO 1.8 The student is able to explain the distribution of electrons using Coulomb’s Law to analyze measured energies.

LO 1.9 The student is able to predict and/or justify trends in atomic properties based on location on the periodic table and/or the shell model.

LO 1.10 Students can justify with evidence the arrangement of the periodic table and can apply periodic properties to chemical reactivity.

LO 1.11 The student can analyze data, based on periodicity and the properties of binary compounds, to identify patterns and generate hypotheses related to the molecular design of compounds for which data are not supplied.

LO 1.12 The student is able to explain why a given set of data suggests, or does not suggest, the need to refine the atomic model from a classical shell model with the quantum mechanical model.

LO 1.13 Given information about a particular model of the atom, the student is able to determine if the model is consistent with specified evidence.

LO 1.14 The student is able to use data from mass spectrometry to identify the elements and the masses of individual atoms of a specific element.

LO 1.15 The student can justify the selection of a particular type of spectroscopy to measure properties associated with vibrational or electronic motions of molecules.
