CHM 1045 Study Guide - Final Guide: Octet Rule, Oxyanion, Ionic Compound
Document Summary
Memorize common element names and symbols: a periodic table with element symbols, atomic numbers, and atomic weights will be provided. So you need to know that he = helium (and other elements designated by instructor) so you can use the periodic table effectively: you will need to move quickly between symbols and names. Write lewis symbols for atoms and ions: know what the lewis symbol represents, use atomic electron configurations and the octet rule to predict charges. Ionic compounds: name ionic compounds based on given formula, predict ionic formulas given ions, see examples 5. 3 and 5. 4. Determine ionic charges from periodic table (chapter 4 review: see figure 4. 12 and. Example 4. 5 in the textbook: given the name of an ionic compound, write the formula, see the follow up practice for examples. 5. 5 and 5. 6: memorize common polyatomic ions (table 5. 5) and element names, know transition metal rules for variable charges.
