All of these subjects are covered in the animated video lessons, which are taught by professional chemistry instructors. Use the video tags to quickly move from one topic to another, or pause and rewind the lessons to clarify information. You can also consult the written transcripts, which include key vocabulary in bold print. There are self-assessment quizzes after each of the lessons. Try printing out the quiz results and using them as handy offline study resources. You can submit any questions on these topics to our experts through your personal dashboard.

ORELA Chemistry: Chemical Bonding - Chapter Objectives

The ORELA Chemistry examination contains 150 multiple-choice questions and includes five content domains. The third domain, Energy and Chemical Bonding, makes up 23% of the full assessment score. This domain evaluates your ability to analyze inter-molecular forces and chemical bonding processes. Apply the concepts you studied in this chapter when answering questions on chemical bonding and other subjects. The exam is part of the Oregon licensure process for a teaching certification in chemistry. The computer-administered examination must be completed in under three hours and 45 minutes.
