Document Summary

Learning objectives chapter 6: reading, read the entire chapter. You should be able to use the octet rule to predict the likely charge the ion of a representative element will form. Ionic- the transfer of electrons form a metal to a nonmetal. Metallic- many metal atoms close to each other sharing electrons: you should be able to describe some of the basic properties of metals and how they relate to the arrangement of metal atoms in a sample. Measure of strength between ions in an ionic bond. You should know the efects of each of these factors speciically. Larger charge= more energy: you should be able to use coulomb"s law to determine the energy of an ion pair. Review objectives: you should be able to use the periodic table to predict the charge of an ion formed from an element in groups 1a, 2a, 5a, 6a, and 7a. You should also memorize the cations (metals) that only have one charge.
