This lesson aligns with the Common Core State Standards:
STANDARD 5 - Matter and Energy
"The competent science teacher understands the nature and properties of energy in its various forms, and the processes by which energy is exchanged and/or transformed.
5A. understands the atomic and nuclear structure of matter and the relationship to chemical and physical properties
5C. understands the cause and effect of chemical reactions in natural and manufactured systems
5E. analyzes the properties of materials in relation to their chemical or physical structures and evaluate uses of the materials based on their properties
5F. explains conservation of mass and energy and explains interactions of energy with matter, including changes in state"
Student note guide to the PowerPoint lesson III in the "Atomic Structure" unit - introductory chemistry. This lesson explains what happens to electrons when atoms gain or lose energy; describes Bohr’s model of the atom and electron energy levels; and identifies the electron cloud model and stable electron configuration.
PowerPoint lessons contain many graphics and links to short videos to further student understanding.
PowerPoint slides also contain notes for the instructor based on students most "frequently asked questions" or FAQ's to help clarify the subject.
A class activity is included at the end of each lesson.
*All PowerPoint lessons; review programs; student worksheets/activities and assessments for this unit can be found under the "Introductory Chemistry Complete Unit III Atomic Structure" zip file folder.
Terms/concepts covered in this lesson include:
energy level movement
electron cloud model
stable electron configuration
