Ch 19 Test Review

Stability in Bonding Vocabulary Chemical Formula Chemically Stable Be able to write the chemical formula of a given compound Chemically Stable Which elements on the periodic table are chemically stable? How can other elements become chemically stable? Chemical Bond What are the two types of bonds that can form between elements?

What type of elements are involved in an ionic bond? What is an ion? How are ions formed? What type of elements are involved in an ionic bond? How are these bonds formed? What type of chemical bond is involved in a covalent bond? How many electrons are involved in single, double, and triple bonds? What is a polar molecule? How do we know what end of the molecule has the (+) or (-) charge?

Writing Formulas and Naming Compounds What does the oxidation number of an element represent? Where are the elements with varying oxidation numbers? What is a polyatomic ion? How do we name binary ionic compounds? What does the term hydrate mean?

WHAT DO YOU NEED HELP WITH? How do we name binary covalent compounds? When do we use the prefixes? Be able to apply dot diagrams to determine the chemical formula of a covalent bond. WHAT DO YOU NEED HELP WITH?
