Activity 8

Quantum Numbers and Electronic Configuration

Objectives

- - (CLO1). Explain basic chemical concepts related to chemical changes, energy, and properties of matter.
  - (MLO2-3). Apply quantum number (principal, angular momentum, magnetic and electron spin) rules to determine allowable values for each type of quantum number and how the quantum numbers relate to atomic orbitals.
  - (MLO2-6). Utilize the periodic table to determine the electron configuration of a neutral atom or an ion.
