Specific heat b. Density c. Polarity d. Hydrogen bonding 2. Why do you need to wrap exposed pipes when the temperature drops below freezing?

4. REMEDIATION: PROPERTIES OF H 2 O 3. Which property is water is essential to providing plants with the vital minerals and nutrients they need? 4. Why does solid water (ice) float? Why is this unique to water?

5. REMEDIATION: PROPERTIES OF H 2 O 5. Water is the only known substance to naturally exist as a solid, liquid and gas. Pick one of these states of matter and explain why it is essential to life on Earth?

6. FORMING AND NAMING IONIC COMPOUNDS OBJECTIVES: 1. PREDICT THE FORMATION OF IONIC COMPOUNDS 2. USING THE NOMENCLATURE RULES, NAME OR PREDICT FORMULAS OF COMPOUNDS WHEN GIVEN AN IONIC COMPOUND

7. GUIDING QUESTION How does road salt keep roads from icing over?

8. WARM UP 1. For each of the following compounds identify which type of bond exists between the elements a. Fe 2 O 3 b. CuCl c. NH 3 d. HgO e. PO 4 3- f. H 2 SO 4 2. Draw the Lewis Structure for: a.Na b.Cl 3.Write the electron configuration for Cl - 4.Write the noble gas shorthand for K+ 5.Which element in its ground state has the same electron configuration as your answer to 3 & 4??

9. IONIC BOND Definition: A bond between a metal and a non-metal; valence electrons are transferred from the metal to the non-metal M + N.M.

10. PROPERTIES OF IONIC COMPOUNDS High Melting & Boiling Points Dissolve in Water  Causes the melting point of water to drop Conduct electricity when melted or dissolved in water Create huge lattice (Chain) Structures If we could zoom in SUPER close

11. MAKING AN IONIC COMPOUND A metal and a non-metal Low Ionization Energy Left side of the periodic table High electronegativity Right side of the periodic table Sodium (Na)Chlorine (Cl) Wants an electron Wants to get rid of an electron

12. THE OCTET RULE Why do atoms gain or lose electrons? The Octet Rule: Definition: Atoms will lose or gain valence electrons to get to 8 (full valence shell) What will happen to each of these elements? (How many electrons will be lost/gained) 1. B 2. Br 3. Mg 4. Li 5. Xe

13. MAKING AN IONIC COMPOUND Sodium (Na)Chlorine (Cl)

14. MAKING AN IONIC COMPOUND Sodium (Na)Chlorine (Cl)

15. MAKING AN IONIC COMPOUND Cation: a metallic element that loses electrons; has a positive charge Anion: a non-metal that is highly electronegative that gains electrons; has a negative charge

16. MAKING AN IONIC COMPOUND Sometimes its not as easy as NaCl… 3 Steps: 1.Draw the Lewis Dot Structure for each element 2.Determine which element will lose electrons and which will gain electrons 3.Draw the transfer electrons from the cation to the anion, add another atom as needed

17. MAKING AN IONIC COMPOUND Show the formation and resulting ions of MgCl 2 1. Draw the Lewis Dot Structure for each element 2. Determine which element will lose electrons and which will gain electrons 3. Transfer electrons from the cation to the anion, add another atom as needed MgCl

18. YOU DO: MAKE IONIC COMPOUNDS Show the formation and resulting ions of: 1. MgS 2. BeBr 2 Write the formula for the ionic compound that results from the bonding of the following elements 1. Cs and I 2. Ca and F 1. Draw the Lewis Dot Structure for each element 2. Determine which element will lose electrons and which will gain electrons 3. Transfer electrons from the cation to the anion, add another atom as needed

19. NAMING TYPE 1 IONIC COMPOUNDS The cation is named first as it appears on the periodic table The anion is named second with the root word plus the suffix “ide” Example: KBr K is the cation Br is the anion Based off our rules we would name this as: Potassium Bromide IMPORTANT: The Cation is an Alkai Metal or Alkaline Earth Metal (NOT H)

20. PARTNER PRACTICE (8 MIN) Name or write the formula for each of the following: 1. LiF 2. NaCl 3. Potassium Chloride 4. BeO 5. Magnesium Sulfide 6. KI  that is an I for Iodine

21. TABLE GROUP ANSWERS: 1. Lithium Fluoride 2. Sodium Chloride 3. KCl 4. Beryllium Oxide 5. MgS 6. Potassium Iodide

22. NAMING TYPE 2 IONIC COMPOUNDS Similar to naming Type 1 Compounds: The cation is named first as it appears on the periodic table The anion is named second with the root word plus the suffix “ide” BUT… Roman numerals are used to represent the charge for the cation IMPORTANT: The Cation is a transition metal

23. NAMING TYPE 2 IONIC COMPOUNDS Example 1: What is the name of the compound Fe 2 O 3 Example 2: What is the formula of Zinc (II) Chloride? IMPORTANT: The Cation is a transition metal

24. PARTNER PRACTICE (8 MIN) Write the name or formula for each compound 1. CuCl2 2. FeCl3 3. Lead (III) Iodide 4. MnF3 5. CoBr3

25. ANSWERS TO PROBLEMS 1.Copper (II) Chloride 2. Iron (III) Chloride 3. PbI 3 4. Manganese (III) Fluoride 5. Cobalt (III) Bromide

26. ACTIVITY: INDEPENDENT PRACTICE HOW? C – None H – Raise hand A – Writing electron configurations M – None P – Recoding answers on left page, head up, reading and thinking through all questions, discussing with group WHAT? 15 minutes  Discuss for 5 minutes  Verify & Review

27. EXIT SLIP HOW? C – No talking H – Raise hand A – Taking exit slip M – In seat P – Completing exit slip without notes and turning in WHAT? (5 MIN) If you finish early, summarize what you learned at the bottom of your notes OR answer today’s guiding question
