Geometries and Polarities of Compounds

Published on 06/09/2008

Activity Overview

In this StudyCard activity, students are asked to describe the geometry and polarity of several molecules and ions. Geometries covered include linear, bent, trigonal planar, trigonal pyramidal, and tetrahedral. Students will need to have discussed the concept of resonance in order to successfully determine the polarity of some of the molecules and ions.

Before the Activity

Students should have access to either the TI-83 or TI-84 family of calculators.

After the Activity

Review student answers:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
