Khan Academy: Vsepr for 5 Electron Clouds

Part II of using VSEPR for five electron clouds including examples for T-shaped and linear molecules. [10:48]

A description of VSEPR with 3 electron clouds and various types of molecules. [12:33]

Learn about VSEPR for six electron clouds, and see examples for octahedral, square pyramidal, and planar molecules. [12:29]

An introduction of VSEPR and molecules with 2 electron clouds. [8:04]

VSEPR for molecules with four electron clouds including examples for tetrahedral, trigonal pyramidal, and bent molecules. [10:05]

An explanation of electron affinity trends across the second period of the Periodic Table. Elements that do not match the trend are identified. [7:28]

A video lecture explaining the movement of the electrons around the nucleus in orbitals. Video describes the orbital's energy shell and shape. Also discussed is the connection of the location of the electrons to the periodic table. [13:37]

Learn about Thomson's cathode ray experiment and the plum pudding model and Rutherford's gold foil experiment.

A detailed look at orbitals and an introduction to electron configuration. [14:31]

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