In this lesson, you will learn about the various types of chemical bonds including ionic, covalent and metallic bonding. By the end of this lesson, students should be able to:
- explain the differences between the formation of ionic bonds and the formation of covalent bonds;
- use Bohr-Rutherford or Lewis structure diagrams to illustrate ionic and covalent bonding;
- explain the Octet Rule;
- explain what a formula unit is and how it applies to ionic crystal lattices;
- define isoelectronic element;
- recognize ball and stick and space-filling models of covalently bonded atoms;
- list examples of molecules exhibiting single, double, and triple bonds;
- predict the type of bond between two atoms based on electronegativity difference (DEN).
Let’s begin by examining how ionic bonds form in the video lesson below. Please take detailed notes as you watch it.
Below is the video lesson on Covalent Bonding. Once again, watch it closely and take down detailed notes.
Tutorials on How to Draw Lewis Structures using Formal Charges
The tutorial below show how to determine the more realistic Lewis structures for polyatomic ions, and for compounds containing atoms with extended octets such as sulfur and phosphorous. Watch them and write detailed notes.
