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!

Investigating the Periodic Table with Experiments - with Peter Wothers

We celebrate 150 years of the Periodic Table and Mendeleev's genius by braving the elements from Argon to Zinc in this demonstration filled show.

You can pre-order Peter's book Antimony, Gold, and Jupiter's Wolf: How the elements were named now:

Dr Peter Wothers is a Teaching Fellow in the Department of Chemistry, University of Cambridge and a Fellow and Director of Studies in Chemistry at St Catharine’s College. Aside from lecturing to Natural Science undergraduates at Cambridge, he is involved with a number of projects bridging the transition between sixth-form and university.

Peter is heavily involved in promoting chemistry to young students and members of the public and has fronted the lectures at the department for the Cambridge Science Festival for over 15 years. He was awarded the 2011 President's Award by the Royal Society of Chemistry for his out-reach activities. He has a keen interest in the history of chemistry and has amassed a significant collection of early works on the subject. Peter presented the 2012 CHRISTMAS LECTURES, The Modern Alchemist

This show was originally titled Braving the Elements and was filmed at the Ri on 15 April 2019.

BIO6 Lecture 2 - Chemistry

Lecture 2 - A basic overview of chemistry, atoms, molecules, covalent bonds, properties of water, acids and bases, and macromolecules.

Covalent Bonding In Carbon Dioxide | Properties of Matter | Chemistry | FuseSchool

Carbon dioxide is a product of one of the most important chemical reactions in the world: combustion.

Combustion is how a lot of people in the world heat their homes and power their cars. It also unfortunately contributes to the greenhouse effect and global warming. The carbon dioxide molecule is formed from one carbon atom and two oxygens. As an element, carbon only has 4 outer shell electrons and oxygen 6.

Double covalent bonds form between the atoms, where two electrons from each atom are shared making 4 bonding electrons in total. The two groups of bonding electrons in carbon dioxide repel each other and this keeps the oxygen atoms as far away from each other as possible. Carbon dioxide is less reactive than water because it has two bonds with each oxygen. This means you need a lot more energy to break the atoms apart. Carbon dioxide's strong double bonds make it very stable and so whenever there are stray carbon and oxygen atoms flying about, they love to get together and form carbon dioxide.

Like water, the bonds in carbon dioxide are POLAR COVALENT, making the carbon atom delta positive and the oxygens delta negative. Although, unlike water, carbon dioxide is not a polar molecule overall.
