Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22

Atoms are a lot like us - we call their relationships bonds, and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about.

If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

Gen Chem II - Lec 2 - Intermolecular Forces And Phases Of Matter

This second lecture is actually the first that covers new material for second semester. First, we take a look at phases of matter, and the differences between each phase by looking at distinguishing properties (Density, Shape, Compressibility, Intermolecular Force strength). Solids and Liquids have intermolecular forces that hold the particles close together. We discuss temperature in terms of molecular motion, and describe phase changes (melting/boiling) as occuring because the molecules are literally shaking too much and result in the interactions being broken. We also discuss pressure effects on phase boiling a little bit. We discuss the direct relationship between intermolecular interactions and melting and boiling points. Then we get into the 3 main types of intermolecular interactions: dispersion (also called temporary dipoles or van der Waals), dipole-dipole and hydrogen bond. We do several examples, including the boiling points of the alkanes. These examples require the lewis structure and molecular shape to be known.

Introduction is filmed on location at Waikiki Beach in Honolulu, HI.

General Chemistry II - Lecture 2 - Intermolecular Forces And Phases Of Matter

These videos are being made because I love teaching general chemistry. Also, I want to provide clear videos that are captioned for the deaf and hard-of-hearing, as well as for international students who use English as a second language (ESL). These video lectures are being used to assess such students as well as hearing students. However, any student of general chemistry should find the lectures very useful. Clear and concise explanations, colorful notes, and simple diagrams are used. All videos are uploaded under the Creative Commons license, so please feel free to use them in any way you.

These videos are hard work on my part, and I enjoy making them. If you continue to watch, then you will not only learn chemistry, but also some interesting things about the state of Hawai'i. Each video normally begins with a short clip taken on location, from somewhere in the Hawaiian Islands. And if you are on the island of O'ahu or happen to visit, then please feel free to stop by Leeward Community College say hello.
Enjoy and Aloha !!!
