Beginning with an overview of how and why chemical bonding occurs, this program explains ionic bonding, describing the common properties of ionic compounds, the Lewis theory, electronegativity, the Pauling scale, ionization energy, and the importance of the valence shell. Using animated graphics throughout, the video also gives relevant information about the periodic table and how specific elements are involved in ionic bonds.

In this video lesson, Paul Andersen demonstrates how to write balanced equations that describe chemical changes. He then gives a short introduction to balancing equations and uses the PHET site to practice this skill.--Publisher.

This program uses the idea of filling electron shells to explain the formation of cations and anions. Electrostatic forces are then used to explain lattice formation, and the relationship between properties and structure is examined. Ionic bonding is introduced by comparing the malleability of silver with the brittleness of rock salt. Demonstrations include the formation of sodium and chloride ions from their respective atoms. Lattice formation is...

"Svante Arrhenius (1859-1927) left his mark on three fields that have become important in 20th-century science: physical chemistry (through his theory of ionic dissociation), climatology (through his model of the magnitude of the greenhouse effect on global warming), and immunochemistry (through his ideas concerning the chemical reactions of serum therapy). He exerted a strong influence on the selection of laureates for the early Nobel prizes in science...
