CHEMICAL NAMES AND FORMULAS CHAPTER 6 (You can talk like a chemist, too) Why is having a naming system for compounds important? List some names of compounds that make up some household items. Know the following prefixes: mono- di- tri- tetra- penta- hexa- hepta- octa- nona- deca- (they are listed as Table 6.5 but start learning them now) What is meant by monatomic? Diatomic? Read 6.1 What is meant by a molecular compound? Molecular compounds are composed of: List some examples of molecular compounds Review the terms ion, cation, anion How and why do metals become cations? How and why do non-metals form anions? What do ionic compounds consist of? Give some examples of ionic compounds. Practice with # 1-4, 6-9 Read 6.2 Review chemical formula Distinguish between a molecular formula and a formula unit Summarize the Law of Definite Proportions Summarize the Law of Multiple Proportions Practice 10-13 Read 6.3 Where do ionic charges come from? Study table 6.2. What is the relationship between group number and charge for the Representative Elements? How are metals with more than one charge represented? Study table 6.3-formula and stock name List examples of metals with more than one charge, their name and their charges What is a polyatomic ion? What do polyatomic ions ending in “-ate” and “-ite” have in common? What is the difference between the formula of an “-ate” ion and an “-ite” ion? Learn Table 6.3 Practice 16-23 Read 6.4 How do you recognize a binary compound? List some binary compounds How do you know when the formula for a binary compound is correct? List some rules/steps for naming and balancing binary compounds. What is a ternary compound? Give some examples of ternary compounds List some step/rules for balancing and naming ternary compounds Practice 28-36 Read 6.5 Compare binary ionic compounds to binary molecular compounds: Similar Different Non-metals can often bond in more than one way. How does on distinguish them, i.e. CO vs CO 2? Again, know table 6.5 Know how and when to use the number prefixes. Read page 578 (in Chapter 20) for acid naming rules, including table 20.1 Summarize (in your own words) the three rules: Know the names and formulas of the first ten alkanes. Look for patterns to recognize them by studying table 25.1 on page 745. Section 6.5 practice 37-44 Chapter 6 Review 46, 47-73 odd. Creating formulas and naming them requires practice-lots of it! Do as much practice as you need to get the concepts down.
