1. Friday December 11 Pickup copy of Naming Rule 1 Ionic Compounds

2. Announcements & Agenda A.Today’s Agenda 1.Debrief yesterday’s Unit 4, Level 2 assessment a.Split classes next week i.Practice/reassess level 2 ii.Work towards/prep level 3 2.Intro/practice to Naming Rule 1 Ionic Compounds 3.Start Polyatomic Ions POGIL

3. Naming Rule 1 Ionic Compounds B.How to determine the subscripts for a rule 1 ionic. 1.Remove the valence electrons from the metal and use them to fill the non-metal ’ s valence shell. a.If both atoms are satisfied, there is a one to one ratio b.If one element is not satisfied, add a second element to take or receive the extra electrons c.Continue the process until all atoms are satisfied i.They have an “octet”

4. Naming Rule 1 Ionic Compounds A.What compound is produced when sodium (Na) reacts with chlorine (Cl)? Na Cl Before and During the Reaction Na Cl +1 After the Reaction Final Formula NaCl

5. Naming Rule 1 Ionic Compounds What compound is produced when calcium (Ca) reacts with nitrogen (N)? Ca N Before and During the Reaction Ca N +2 -3 After the Reaction N -3 Ca +2 Ca +2 Ca N Final Formula Ca 3 N 2

6. Naming Rule 1 Ionic Compounds A.Metal keeps its name B.Non-metal adds –ide 1.Example: a.CaF 2  Calcium Fluoride b.NaCl  Sodium Chloride c.K 2 S  Potassium Sulfide C.Applies to all ionic compounds with a non-metal 1.Rules 1 & 3 2.We’ll learn a different naming construction for Rules 2 & 4 that involved polyatomic ions later
