CHEM107: Inorganic Chemistry

Unit 1: Introduction to Inorganic Chemistry   In this unit, you will learn the different parts of a hydrogen atom wavefunction and discover how wavefunctions relate to atomic orbitals and their relative energies.  You will also learn how to determine the atomic term symbols from a given electronic configuration and use Hund’s rules to predict the electronic ground state.  This unit ends with a comprehensive analysis of trends in the periodic table.  You will learn how to rationalize the exceptions in these periodic trends.  

Unit 1 Time Advisory
This unit should take you approximately 6 hours to complete.

☐    Subunit 1.1: 2 hours

☐    Subunit 1.2: 3 hours

☐    Subunit 1.3: 1 hour
