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. 18 minutes
