Electron affinity is defined. Electron affinities of various elements are compared. [11:39]

A video lecture discussing the trends on the periodic table dealing with ionization energy, electronegativity, metallic nature, and atomic radius size. The video shows how electronegativity increases to the top right of the periodic...

The energy to remove an electron, or ionization energy, is explained. [12:13]

Explanation of the ionization energy required for different groups on the Periodic Table. [10:18]

A narrated screencast which illustrates the ionization energy changes over representative elements on the periodic table. [3:21]

Through a series of video lectures and some review questions, learn about the Bohr model of the atom and the periodic table of elements. [7:51]

Definition of ion and ionization energy, and trends in ionization energy across a period and down a group. [10:01]

In this video, Paul Andersen explains why atoms in the periodic table show trends in ionization energy, atomic radii, electronegativity and charge. All of these trends are explained through Coulomb's Law. A brief description of Dmitri...

Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted in the formation...
