Winter Break Survey

We began the day with the Lesson 37 PowerPoint.  Students learned about electron domains and how they affect the shape of a molecule.  They then worked in pairs on the Lesson 37 Worksheet.

Key ideas:

• noble gases (single atoms) are visualized as points
• molecules consisting of two atoms (i.e. hydrogen fluoride) are linear
• molecules consisting of three atoms can be bent (H2O) or linear (CO2)
• molecules consisting of four atoms, like ammonia (NH3) are called pyramidal
• molecules consisting of five atoms, like methane (CH4) are called tetrahedral
