1 Do Now: Creative Assignment – You are a CATION – You are writing to an ANION Write a short Love Note about the topic: “Let’s bond together” to You have 5 minutes!!!!! HAVE YOUR HW OUT ON YOUR DESK!

2 Trade Papers and Check

3 Check Answers

4 Steps to NAMING ionic compound: 1.Name the cation 2.Name the anion and change the ending to “ide” -Group 17: ine  ide -Oxide -Sulfide -Selenide -Phosphide -Silicide -nitride -hydride 3. Add (roman numeral) if the cation is a transition metal

5 1.Calcium and Bromine2. MgS Naming Ionic Compounds Examples: Steps: 1.Name the cation 2.Name the anion and change the ending to “ide” -Group 17: ine  ide -Oxide -Sulfide -Selenide -Phosphide 3. Add (roman numeral) if transition metal

6 Try #1-4 on Ionic Formulas HW

7 1.FeO2. CrBr 3 Naming Ionic Compounds w/ Transitional Metals Examples: Steps: 1.Name the cation 2.Name the anion and change the ending to “ide” -Group 17: ine  ide -Oxide -Sulfide -Selenide -Phosphide 3. Add (roman numeral) if transition metal **Work Backwards**

8 Name the following in your notebook: 1. Pb 3 N 2 2. CdBr 2 3. NiI 3 Then TRY #12-14 from formula HW

9 Steps to NAME an ionic compound with Polyatomic Ions: 1.Name cation (or ammonium  only “+” p.i.) 2.Name polyatomic ion *** DO NOT CHANGE ANYTHING*** Example: Mg(NO 3 ) 2

10 Molecular / Covalent Compounds A compound that is composed of 2 or more non-metals How to recognize an molecular/covalent compound … Anion and anion Nonmetal and nonmetal - and -

11 Steps to NAMING a covalent compound : 1.Name the first element in formula 2.Name second element in the formula and change endings to “ide” 3.Add prefixes before each element name (according to the subscripts) 4.EXCEPTION  never use mono for the 1 st element

12 Prefixes to MEMORIZE NumberPrefix

13 1.CO 2 2.N 3 F 8 Naming Covalent Compounds Examples: Steps: 1.Name first element in formula 2.Name second element and change endings to “ide” 3.Add prefixes (according to how many there are) 4.EXCEPTION  never use mono for the 1 st element

14 Try #9-11on Naming Covalent Compounds Worksheet

15 Steps to Write the Formula for a covalent compound : 1.Write the symbol for the first element in the compound. 2.Write the formula for the second element in the formula. 3.Add the prefixes as subscripts for each element. NO REDUCING NO CHARGES Ex 1: Carbon MonoxideEx 2: Diphosphorus tetrachloride
