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
•Ternary acid
•Base
- H – nonmetal
- H – Polyatomic ion
- metal ion – OH

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…

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.

Copper (I) persulfate
Name the second ion.
Name the first ion.
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.

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.

Write the formula/symbol and charge of each ion.
Balance the charges by supplying subscripts.
Since Al is +3 and NO
