Ionic Bonding

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 explained in terms of electrostatic repulsion and attraction. Models of different lattice structures are illustrated and explained in terms of the relative sizes of ions.
