Pickup copy of Naming Rule 1
Ionic Compounds
Announcements & Agenda
A. Today’s Agenda
1. Debrief yesterday’s Unit 4, Level 2 assessment
a. Split classes next week
i.
ii.
Practice/reassess level 2
Work towards/prep level 3
2. Intro/practice to Naming Rule 1 Ionic Compounds
3. Start Polyatomic Ions POGIL
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.
b.
c.
If both atoms are satisfied, there is a one to one ratio
If one element is not satisfied, add a second element to take or
receive the extra electrons
Continue the process until all atoms are satisfied
i.
They have an “octet”

Final Formula
Naming Rule 1 Ionic Compounds
A. Metal keeps its name
B. Non-metal adds –ide
1. Example:
a. CaF2  Calcium Fluoride
b. NaCl  Sodium Chloride
c. K2S  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
