Bonding in Chemistry - Chapter Summary and Learning Objectives

In this chapter, you'll learn how atoms, the most basic form of matter, are attracted to each other and develop chemical bonds. You'll also find out how atoms can be chemically transformed into ions by gaining or losing the subatomic particles known as electrons. As you progress through the videos, the instructor will introduce you to several scientific theories, including Octet and VSPER (valance shell electron pair repulsion) rules, which can be used to describe the creation of ions and predict molecular shape.

In this chapter, you'll also receive some scientific drawing lessons, learn how to create symbols of elements and diagram the behavior and structure of electrons in molecules. Carbon-based or organic molecules will also be discussed as well as why 'seas' of electrons make metals such good electrical conductors. When you have finished watching the videos and taking the self-assessment quizzes, you should be able to:

  • Identify and discuss the different types of chemical bonds
  • Understand the differences between polar and non-polar molecules
  • Explain how the Octet rules can be used to explain the formation of ions
  • Diagram Lewis structures of covalent compounds and ions
  • See how intermolecular forces, such as dipole-dipole, can affect boiling and melting points
  • Use scientific theories to predict molecular shape
  • Understand atomic orbitals and how combined orbitals can lead to hybridization
  • Write a formula for an ionic compound.
