Khan Academy: Structure and Bonding: Condensed Structures

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]

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

The Pauling Scale is used to understand bonding due to electronegativity. Bond types are classified. [11:39]

Understand that cell size is limited by volume to surface area ratio in this video. Learn that if cells become too big it cannot take in nutrients and get rid of waste fast enough. [8:55]

How do we go from cell to a multicellular organism? This video will explore the components of the extracellular matrix that connect to the inside of the cell. [6:54]

This video tries to conceptualize the size of cells. [7:19]

Article takes a look at the different components (protein, lipid, cholesterol, and carbohydrate) of the plasma membrane, examining their roles, their diversity, and how they work together to make a secure boundary around the cell.

Sal Khan presents structures of organic molecules using line (or line-angle) diagrams. [7:28]

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