5 The Electron

Overview

Objectives

  • Energy levels
  • s, p, d, and f orbitals
  • Valence electrons
  • Stable ions
  • Describe that spectral lines are the result of transitions of electrons between energy levels.
  • Describe the relationship between wavelength, frequency, and energy.
  • Use Planck's constant to solve for energy or frequency.

Academic Standards


C.1.32  Describe the possible subatomic particles within an atom or ion.  Identify the location, charge, and mass of protons, neutrons, and electrons.

C.1.33Use the element's location in the Periodic Table to determine its number of valence electrons, and predict what stable ion or ions and element is likely to form in reacting with other specified elements.
  • Determine electron configuration by position on periodic table.
  • Construct Lewis-dot structures for elements using the periodic table.
C.2.6  Explain that the application of the laws of quantum mechanics to chemistry by Linus Pauling and others made possible an understanding of chemical reactions on the atomic level.
