Unit 5: Electronic Structure

A good understanding of the organization of the electrons around the nucleus and the forces between protons and electrons within an atom is crucial to understand why elements behave differently. Let’s look at that…

Objectives:

  1. I know what electromagnetic radiation is and I can calculate with the properties wavelength, frequency, and energy.

  2. I know the different types of electromagnetic radiation in the spectrum.

  3. I know how electrons can produce light and can explain this process with the Bohr atomic model.

  4. I know the orbital organization of the quantum mechanical model.

  5. I know how electrons are organized within orbitals (Aufbau principle, Pauli’s exclusion principle, Hund’s rule)

  6. I know that the electron organization shapes the periodic table.

  7. I can write electron configuration (full and abbreviated) using the periodic table.

  8. I know what Coulombic forces are and what factors can change them.

  9. I know that the electron organization determines the behavior of elements and I can describe this with the terms atomic size, metallic character, ionization energy, and electronegativity.
