Khan Academy: Electronegativity and Bonding

Explanation of how differences in electronegativity effect chemical bonding. Bonds are classified by various bonding types.

Learn how to classify bonds as covalent, polar covalent or ionic by using the differences in electronegativity in this video. Video explains the Pauling scale to find the electronegativity differences in bonding. [11:38]

Learn that a sp3 hybridized orbital is a combination of s and p orbital in this video. Also see an example of when a hybridized orbital exist by looking at when carbon forms a sigma bond. [16:22]

Learn the difference between electronegativity and electron affinity. Group and period trends are also discussed in relation to atomic radii. [9:54]

A video exploring the definition of nucleophilicity. Learn that nucleophilicity is the ability of an atom, ion, or molecule to lose their extra electron and bond. Also the video explains how to find the strength of the nucleophile. [13:54]

In this video learn how to take a Lewis dot structure to a partially condensed structure to a condensed structure. Video gives an example of this process. [6:48]

Khan Academy presents the rules and processes of naming alkanes and cycloalkanes. [12:34]

Electronegativity is defined and compared to electron affinity. Trends based on groups and periods are also explored. [9:54]

Explains what covalent bonds are and the difference between them and ionic bonds. Discusses the properties of polar and non-polar covalent bonds, and single and multiple covalent bonds, and gives analogies and examples of how covalent...

Article defines and explains compounds which are either ionic or covalent and molecules which are the simplest unit of a covalent compound. Molecules can be represented in many different ways.
