  1. Review of Varying the Number of Oxygens in a Polyatomic Ion

  2. Professional Hittite Engineer Exam Calculate the smallest limb diameter on a persimmon tree that will support a 10-pound possum.

  3. Naming Various Polyatomic Ions:At the conclusion of our time together, you should be able to: Name 3 different polyatomic ions by adding or subtracting oxygens Use these various ions in a compound and name them or write them

  4. 6 Types Of Chemical Compounds • Binary ionic - metal ion – nonmetal ion • Binary molecular - two nonmetals • Ternary ionic - at least one ion is a polyatomic ion • Binary acid - H – nonmetal • Ternary acid - H – Polyatomic ion • Base - metal ion – OH

  5. Things You Can LearnFrom Your Dog!! When your loved one comes home, run to greet him/her. Eat with gusto to show your appreciation for the meal.

  6. Let’s learn some variations on the polyatomic ions… • The standard ions that you have on your handout that end in –ate can be changed by adding or subtracting oxygens to form 3 more ions.

  7. Let’s see what happens when we add or subtract oxygens… Perbromate Bromate Bromite Hypobromite

  8. Let’s try it again… Persulfate Sulfate Sulfite Hyposulfite

  9. New Element On The Periodic Table Element: Woman Symbol: Xx AtomicMass: 120 (More Or Less)

  10. New Element On The Periodic Table (cont.) PhysicalProperties of Xx: Generally round in form. Boils at nothing and may freeze anytime. Melts whenever treated properly. Very bitter if not used well. ChemicalProperties: Very active. Possesses strong affinity to gold, silver, platinum, and precious stones. Violent when left alone. Able to absorb great amount of exotic food. Turns slightly green when placed beside a better specimen. Ages rapidly.

  11. New Element On The Periodic Table (cont.) Usage of Xx: Highly ornamental. An extremely good catalyst for disintegration of wealth. Probably the single most powerful income reducing agent known. Caution: Highly explosive in inexperienced hands.

  12. Naming Compounds with Polyatomic Ions as Cations and Anions Name the first ion. (NH4)3PO3 Ammonium Name the second ion. phosphite

  13. Shade Metals with Oxidation Numbers that Change (Need Roman Numeral)

  14. Naming Trends M-NM Standard NM-NM Greek M-NM Roman

  15. Cu2SO5 Name the first ion. You should realize that you need a Roman Numeral since copper is a transition metal. Copper (I) persulfate Name the second ion. The Roman Numeral is the same as the charge. What is the charge? The charge of persulfate is -2. Since there are two coppers, the charge of the copper must be +1.

  16. Euphemisms in ScienceWe all know that some politicians and government spokesmen use certain euphemistic phrases to give an aura of respectability to descriptions of events or actions which would be offensive when expressed in plain English. The following is a list of Euphemisms in Science and their translations into plain English. “It has long been known...” I haven't bothered to look up any references!

  17. Aluminum nitrite First, you can tell from the name that there is a polyatomic ion present (nitrite). All binary ionic compounds have suffixes of –ide. Al3+ NO2- Al(NO2)3 Write the formula/symbol and charge of each ion. Balance the charges by supplying subscripts. Since Al is +3 and NO2 is -1, you need a total of 3NO2- to balance one Al3+ Since you will need a subscript of 3 for NO2-, you need to put this in parentheses with the 3 outside.

  18. Lead (IV) peracetate Write the formula/symbol and charge of each ion. Pb4+ C2H3O3- Balance the charges by supplying subscripts. Since Pb is +4 and C2H3O3 is -1, you will need 4 C2H3O3-1 to balance 1Pb+4 Pb(C2H3O3)4 Write the formula/symbol and charge of each ion. Calcium phosphite Ca2+ PO33- Balance the charges by supplying subscripts. Since Ca is +2 and PO3 is -3, you will need 3 Ca+2 to balance 2 PO3-3 Ca3(PO3)2

  19. Strategy For Naming Ternary Ionic Compounds.

  20. Naming Various Polyatomic Ions:Let’s see if you can: Name 3 different polyatomic ions by adding or subtracting oxygens Use these various ions in a compound and name them or write them

  21. Chemical Compound Quiz Hypochlorous acid helps get the laundry white and bright. What is the common name? Bleach

  22. Exit Quiz Al3+ combines with sulfite (SO3)2– to make aluminum sulfite. Write the chemical formula for aluminum sulfite.

  23. Exit Quiz Answer 3+ 2- Al (SO3) 2 3

  24. Let’s Try Another One: Manganese (IV) hypophosphite 3- 4+ (PO2) Mn 3 4

  25. Let’s Try One More: Manganese (IV) carbonite 4+ 2- (CO2) Mn 2 4 Mn(CO2)2

  26. Exit Quiz Lithium hydroxide Manganese (III) hydroxide Calcium hydroxide Copper (II) hydroxide Potassium hydroxide

  27. Exit Quiz Sodium persulfate Sodium sulfate Sodium sulfite Sodium hyposulfite

  28. Exit Quiz Iron (II) percarbonate Iron (II) carbonate Iron (II) carbonite Iron (IV) carbide

  29. Hittite News: Down home in Hittiteville, folks now go to some movies in groups of 18 or more. They were told 17 and under are not admitted.
