Name ______________________________________________ Date _______________ Chapter 7 Study Guide Ionic and Metallic Bonding• What is a valence electron? What is a core electron?• How do you determine how many valence electrons an element has by looking at its position on the periodic table?• Know how to write electron dot diagrams for elements and their ions• What is the octet rule?• Know how many electrons need to be gained or lost to satisfy the octet rule.• What kinds of ions do metals form? How do they form them?• How do the electron configurations of ions compare to noble gas electron configurations?• What forms ionic bonds?• What types of elements are able to form ionic bonds?• Know how to write the formula unit for an ionic compound• What must the overall charge of an ionic compound be in a formula unit?• What are the 3 properties of ionic compounds?
• When do ionic compounds conduct electricity?• What does it mean for metals to be malleable?• What does it mean for metals to be ductile?• Besides metals being malleable and ductile, what are two other properties that metals have?• Using the metallic bonding theory, why do metals have the properties that they do?• How are atoms arranged in metallic solids?• Why is it possible to bend metals but not ionic crystals?• What are alloys? Why are alloys important?
