Varying the Number of Oxygens in a Polyatomic Ion

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

Naming Various Polyatomic Ions: At the conclusion of our time together, you should be able to: 1. Name 3 different polyatomic ions by adding or subtracting oxygens 2. Use these various ions in a compound and name them or write them

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

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

New Element On The Periodic Table Element : Woman Symbol : Xx Atomic Mass : 120 (More Or Less)

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.

Let’s see what happens when we add or subtract oxygens… IonName BrO 4 1- BrO 3 1- BrO 2 1- BrO 1- Perbromate Bromate Bromite Hypobromite

Let’s try it again… IonName SO 5 2- SO 4 2- SO 3 2- SO 2 2- Persulfate Sulfate Sulfite Hyposulfite

New Element On The Periodic Table (cont.) Physical Properties of Xx : Generally round in form. Boils at nothing and may freeze anytime. Melts whenever treated properly. Very bitter if not used well. Chemical Properties : 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.

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.

( NH 4 ) 3 PO 3 Name the first ion. Name the second ion. Ammonium phosphite Naming Compounds with Polyatomic Ions as Cations and Anions

Cu 2 SO 5 Name the first ion. Copper You should realize that you need a Roman Numeral since copper is a transition metal. 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. (I)persulfate Name the second ion.

Euphemisms in Science We 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!

Aluminum nitrateFirst, you can tell from the name that there is a polyatomic ion present (nitrite). All binary ionic compounds have suffixes of –ide. Write the formula/symbol and charge of each ion. Al 3+ NO 2 - Balance the charges by supplying subscripts. Since Al is +3 and NO 2 is -1, you need a total of 3NO 2 - to balance one Al 3+ Since you will need a subscript of 3 for NO 2 -, you need to put this in parentheses with the 3 outside. Al(NO 2 ) 3

Lead (IV) peracetate Write the formula/symbol and charge of each ion. Pb 4+ C 2 H 3 O 3 - Balance the charges by supplying subscripts. Since Pb is +4 and C 2 H 3 O 3 is - 1, you will need 4 C 2 H 3 O 3 -1 to balance 1Pb +4 Pb(C 2 H 3 O 3 ) 4 Calcium phosphite Write the formula/symbol and charge of each ion. Balance the charges by supplying subscripts. Since Ca is +2 and PO 3 is -3, you will need 3 Ca+2 to balance 2 PO 3 -3 Ca 2+ PO 3 3- Ca 3 (PO 3 ) 2
