1. Naming Ions

2. Name That Celebrity

3. Norma Jean Mortenson
Marilyn Monroe

4. Eric Bishop
Jamie Foxx

5. Reginald Kenneth Dwight
Elton John

6. Destiny Hope Cyrus
Miley Ray Cyrus

7. Caryn Johnson
Whoopi Goldberg

8. Paul Hewson
Bono

9. When an atom becomes an ion, it’s name changes!
Just like how many celebrities change their name when they become famous!

10. Monotomic Ions
Monotomic ion: a single atom with a positive or negative charge resulting from the loss or gain of one or more electrons.
Cations:
The names of the elements in Group1A, 2A, 3A metals are the same as the name of the metal followed by the word ion or cation.
Example: Li+
Name: Lithium ion or Lithium cation
Ca2+, Calcium ion/cation

11. Practice Name the following: Write the chemical formula: Na+ Sr2+ Ba2+
Beryllium cation
Potassium cation

12. Monotomic Ions
Note: The charge of any ion of a Group A nonmetal (right side of P.T.) is determined by subtracting 8 from the group number.
Anions: Start with the stem of the name and end –ide.
Example:
Flourine: flouride, F-
Oxygen: oxide, 02-
Nitrogen: nitride, N3-

13. Practice
Name that anion
Sulfur, S2-
Phosphorus, P3-
Arsenic, As3-

14. Ions of Transition Metals
Transition metals (groups 1B -8B) form more than one cation with different ionic charges.
The charge of cations of many transition metal ions must be determined from the number of electrons lost.
Example: Iron can be Fe2+ or Fe3+
Use Stock system: place a Roman numeral in parenthesis after the name of element to indicate the numerical value of the charge.
Fe2+ Iron(II) ion
Fe3+ Iron(III) ion

15. Practice!
Name these transition metal ions
Cu+
Cu2+
Cr3+
Mn2+

16. Polyatomic Ions Ions composed of more than one atom
Tightly bound groups of atoms that act as a unit and carry a charge.
Most of the names end in – ate or –ite.

17. Polyatomic Ions
When the formula for a polyatomic ion begins with H (hydrogen), you think of the H as representing a hydrogen ion (H+) combined with another polyatomic ion.
Example: hydrogen carbonate
H+ + CO3-2 = HCO3 -

18. Naming Scavenger Hunt!

19. Naming Ionic Compounds
If Representative Element (Groups 1A, 2A, or 3A – 7A)
1. Name the cation
2. Name anion, change ending to –ide
Ex: MgO Magnesium Oxide
Ex: K3P Potassium Phosphide

20. NaF-
LiCl-
MgO-

21. Naming Ionic Compounds with PAI’s
1. Name Cation
2. Name PAI (Anion)
Ex: KNO3 Potassium Nitrate
Ex: MgCO Magnesium Carbonate
Reminder: Never break up PAI’s!

22. Practice
Ca(ClO)2
Na2SO4
Na2SO3

23. Naming Ionic Compounds with Transition Metals (Group B Metals)
Remember: They can have different charges (+1, +2, +3, +4)
1. Name metal using Stock system (Roman numeral)
2. Name Anion (ending in –ide)
3. Figure out the charge of the cation based on the charge of the anion
Ex: FeCl2
-Options for Iron: Fe2+ or Fe3+
-We know Chloride has a 1- charge (In this example two Cl- ions are present, yielding a 2- charge)
-So, Iron needs to balance the 2- charge to create a neutral ionic compound)
-Choose Fe2+
Iron(II) Chloride

24. Practice
Fe203
Mn3(PO4)2
You always want to achieve a neutral compound, so balance charges when necessary!

25. Practice!
Al2O3
Cu3N2
PbS2
K2SO4
Sr(OH)2
Fe2(CO3)3

26. Step One: Translate the name into ions
Going backwards
Copper(II) Fluoride
Step One: Translate the name into ions
The cation is copper(II) and the anion is fluoride. Recognize that Copper(II) is Cu2+ and Fluoride is F-.
Step Two: Put brackets around the ions, but leave the charges on the outside
In this case, copper(II) would be [Cu]2+ and fluoride would be [F] NEVER change anything in brackets!
Step Three: Cross the charges
The charge on the cation is the number of anions you have, and the charge on the anion is equal to number of cations you have.
CuF2 Copper(II) Fluoride

27. Write the Chemical Formula!
Potassium Flouride
Ammonium sulfate
Magnesium Iodide
Copper(II) sulfite

28. More Practice! Copper(II) Acetate Sodium Hydroxide Lithium Oxide
Lead(II) Nitrate
